Customizable HTML Select

1 day ago (developer.chrome.com)

So after decades of developer pain, all we're getting is a better select?

Where is the native HTML datagrid (that supports sorting, filtering, paging, downloading, row/column freezing, column resizing and re-ordering)?

Where are the native HTML Tabs control? Image selector, resizer/cropper, and uploader? Toggle button? etc.

We can't even get text input to respect autocomplete directives properly. On the major browsers, giving your user id and password inputs nonsensical names seems to be required, along with numerous other hacks, to ensure that when a user is registering, the form is not auto-completed with saved passwords.

HTML is really holding us back right now.

  • Progress is very gradual in this space, but browser vendors are working on a lot of this stuff in the Open UI W3C community group. https://open-ui.org/

    https://open-ui.org/components/combobox.explainer/ https://open-ui.org/components/switch.explainer/

    > Where are the native HTML Tabs control?

    You implement tabs today (aka accordions) with `<details name="tab">`. https://developer.mozilla.org/en-US/docs/Web/HTML/Element/de... "This attribute enables multiple `<details>` elements to be connected, with only one open at a time. This allows developers to easily create UI features such as accordions without scripting."

    You do have to write some CSS to align tabs horizontally, but it's fine.

    > Image selector?

    Use `<input type="file" id="avatar" name="avatar" accept="image/png, image/jpeg" />`. Opens the OS photo picker on mobile. You can style it however you like.

    > We can't even get text input to respect autocomplete directives properly.

    "Properly" seems to be doing a lot of work there. "autocomplete" works fine, but it's annoying to get it right, and this kinda can't be fixed, because HTML is under a lot of backwards-compatibility constraints.

    If you have autocomplete bugs to file, file them, and maybe convince the Interop group to focus on this issue. Their priorities for 2025 were just announced, but there's always next year. https://web.dev/blog/interop-2025

    • > it's annoying to get it right, and this kinda can't be fixed, because HTML is under a lot of backwards-compatibility constraints

      Sorry, but this seems like a wild mischaracterisation, at least in regards to the problems I've had with users on Chrome. In our experience, Chrome aggressively shows an autofill prompt on almost every input it can. It also ignores the specced autocomplete=off attribute. We have observed Chrome showing a password prompt on an <input type=number> which is just bonkers. It is not hard NOT to do this.

      The Chrome team thinks whatever heuristic they're using is better than allowing developers, or even end users, to control filling behaviour.

      https://issues.chromium.org/issues/41163264 https://issues.chromium.org/issues/41239842

      (By "autofill" I don't necessarily mean the input is automatically filled without user interaction, but sometimes a promotions shown with e.g. account login details or an address.)

      The argument has been that developers are naughty and turn off autocomplete inappropriately, which worsenes accessibility. But I've never seen e.g. a tooltip option in a browser to let me, the user, fill in details when I know they're appropriate? I am merely at the whim of the Chrome algorithm.

      This just selects the image. 99 times out 100, you want to do the same things with the image data: adjust it in some way, and save it to object storage or something. The file input is too primitive for this. And this is the theme all over, HTML control remain too primitive to do any real world rih UI with, which leads to the proliferation of JS UI libraries.

      Autocomplete "bugs" abound aplenty, some of which will make your jaw drop. I've been testing with Chrome and Firefox. The length to which browsers will go in a misguided attempt to be clever with auto-complete is frankly absurd. So I'm not sure they are "bugs" so much as they are a wilful refusal by browser vendors to follow the spec.

  • Datagrid is mysteriously missing on several newer desktop UI frameworks too, which effectively makes those frameworks ill-suited for a whole range of desktop applications. The only place reasonably batteries-included versions of those widgets can be found are in the old guard toolkits like AppKit, win32, MFC, Qt, GTK, etc.

  • > Where is the native HTML datagrid

    Which parts of a datagrid should a browser provide? I'm familiar with AG Grid [1] and the API surface is enormous. Aligning browsers on a feature set would be challenging.

    Maybe there's a core set of functionality, like Flutter's GridView or QML https://doc.qt.io/qt-6/qml-qtquick-gridview.html.

  • Imo it’s not html, it’s browser vendors. There’s a decent specification for the `autocomplete` attribute: https://developer.mozilla.org/en-US/docs/Web/HTML/Attributes...

    • It is actually a reaction to websites doing stupid things to try and prevent password auto-fill. The sites are fighting against security in a misguided attempt to improve security, so the browser vendors added a bunch of heuristics to try and correct these situations and you end up with the mess we have.

  • RE autocomplete in Chrome. The only thing we've found to work reliably is ensuring that all inputs are in form elements. Any inputs outside forms are going to have inappropriate autocomplete prompts. It's extremely annoying but at least this works for now.

    (I say "for now" because who knows when the Chrome team will change their heuristic?)

  • > Where is the native HTML datagrid

    Imagine a world where instead of letting IE die, microsoft decided to add a <XLS> tag in the early 2000. The most used nocode database in the world directly in the browser. In 2000.

  • HTML can never be meaningfully improved, that fact is at the heart of the current attitudes by the browsers. We are 20 years into the takeover from the W3C and still can't even do a PUT request without JS, nevermind anything approaching even one tenth of the capability of XForms.

    The best we'll get is little improvements like this which everyone will ignore because ChatGPT will recommend some react component instead.

  • I think some of this stuff isn't the responsibility of HTML. If HTML already has a full autocomplete spec, isn't it the fault of browsers/extensions/OS if the implementation is broken? Or are you saying the spec is too ambiguous?

    A lot of stuff becomes redundant under the framing that HTML is designed to provide semantics, not a user interface. How is a toggle button different from a checkbox? How are tabs different from <details>, where you can give multiple <details> tags the same name to ensure only one can be expanded at a time?

    Image manipulation is totally out of scope for HTML. <input type="file"> has an attribute to limit the available choices by MIME type. Should there be special attributes for the "image" MIME type to enforce a specific resolution/aspect ratio? Can we expect every user agent to help you resize/crop to the restrictions? Surely, some of them will simply forbid the user from selecting the file. So of course, devs would favor the better user experience of accepting any image, and then providing a crop tool after the fact.

    Data grid does seem like a weak spot for HTML, because there are no attributes to tell the user agent if a <table> should be possible to sort, filter, paginate, etc. It's definitely feasible for a user agent to support those operations without having to modify the DOM. (And yes, I think those attributes are the job of HTML, because not every table makes sense to sort/filter, such as tables where the context of the data is dependent on it being displayed in order.)

    Generalized rant below:

    Yes, there are pain points based on the user interfaces people want to build. But if we remember that a) HTML is a semantic language, not a UI language; and b) not every user agent is a visual Web browser with point-and-click controls, then the solution to some of these headaches becomes a lot less obvious. HTML is not built for the common denominator of UI; it's built to make the Web possible to navigate with nothing but a screen reader, a next/previous button, and a select/confirm button. If the baseline spec for the Web deviates from that goal, then we no longer have a Web that's as free and open as we like to think it is.

    That may be incredibly obvious to the many Web devs (who are much more qualified than me) reading this, but it's not something any end user understands, unless they're forced to understand it through their use of assistive technology. But how about aspiring Web devs? Do they learn these important principles when looking up React tutorials to build some application? Probably not—they're going to hate "dealing with" HTML because it's not streamlined for their specific purpose. I'm not saying the commenter I'm replying to is part of that group (again, they're probably way more experienced than me), but it reminded me that I want to make these points to those who aren't educated on the subject matter.

  • I'm not finding any of those proposals on the whatwg html repo, mind linking them?

    • That's my point, they are not on the roadmap, although they absolutely should be, IMO.

      The W3C and WHATWG have their priorities mixed up.

  • Right? There are already dozens of deprecated elements, just deprecate these too and give us new ones that actually do what they're supposed to do and don't require us to know the entire history of HTML just to do a dang <select> that isn't ugly.

  • Apple’s webkit team killed customised built-in elements by refusing to implement them on ideological grounds, so you get a dripfeed of piecemeal solutions instead.

    • Apple is actively sabotaging the web for a number of years now. They don't want web apps to be able to compete with native iOS apps.

      And they prohibit different browsers from the app store, so users don't even have a choice.

  • > Where is the native HTML

    14 years have been wasted on making web components happen, and they still offer... nothing really, and people already advise to skip large portions of their specs (Shadow DOM) even if you adopt them.

    Imagine if the literally millions of dollars spent of them were spent on something like https://open-ui.org/ (started by Microsoft of all companies and now also completely overrun by Googlers)

    • I find web components very useful. Yes, I avoid shadow DOM as it only makes things more complicated for me, but having bits of functionality grouped in a new tag is great.

  • Please forgive my tangential rant on the DOM. You have an input field where type=number and when you read it with .value() you get a string. Cmon man.

    • There is .valueAsNumber. input.value returns a string, regardless of the input type. Making the return type dynamic would be worse, imo.

If this will stop the proliferation of terrible JavaScript implementations of <select>, I'm here for it.

  • I know LoC is a terrible metric, but it always shocks me that things like react-select require 30k LoC.

    21% the size of the code of the Apollo Lander to configure/style a select dropdown.

    • react-select does a lot more than style the select though, so even after this new standard for customizable selects is supported everywhere, react-select will still have about the same level of complexity as it does now.

  • I salute your optimism. Really, this just gives developers more options to make designers lives more miserable, and vice-versa.

    • My thought was it is giving designers more options to make users’ lives more miserable.

  • I am honestly just blown away Google invested effort into a web standard that actually improves the web versus the dozens of web platform projects designed to let websites slurp more data.

    This is something I actually look forward to being able to use when Firefox gets it.

  • There’s got to be a happy medium between using canvas to make the controls you actually want and browser-provided one-size-fits-nobody controls. I really thought MS was onto something with Silverlight’s with XAML but that died.

Ah, customizable for web developers, not end users.

(And yes, I'm still bitter about you all wrecking my scroll bars.)

  • You can override styling with user stylesheets. On desktop. Need the same for i{,Pad}OS.

    • There are some iOS apps that work as Safari extensions and enable Greasemonkey scripts. I use one called Userscripts.

  • I think that CSS is excessive, that I often disable it and that the excessive design means that sometimes the way to fix it is to add more stuff, which just makes it more messy. (In many cases, it would be helpful to put things that only the end user controls and that document author does not control. Yet, they don't really design them for that very well.)

I've been doing front-end since the days of IE5 and I'd be rich if I had a penny for every time I've had to do a custom "select". It's a pain to use third-party libraries for this, but it _is_ a solved problem and doesn't require that much extra code.

  • I think we should welcome all efforts to have a standardized, modern select component in the HTML spec. Would save a lot of trouble.

  • Even with an average software engineer compensation, you probably got paid a lot more than a penny for every custom "select" you implemented :)

  • Yeah the problem is when you need to create a custom select without using a 3rd party library, and you want to make sure the interactions are accessible and up to parity with native selects. Then you have to add tons of event handlers, aria attributes, refs for handling outside clicks, etc etc.

  • Which libraries have solved this problem? I recently tried several of the most recommended standalone JS libraries for implementing a <select> with icons and a custom layout, but each single one of them was seriously lacking in some way.

  • It's not a solved problem. There are maybe two libraries out there that are customizable, performant, and don't break things like keyboard navigation and accessibility

I spent days building this little perfect dropdown select thing, that is a hundreds lines of code and even more docs explaining what the hell is going on. Someone wasted the same amount of time before me. Someone else spent a lot of time before them. And so on.

I wish we have had more browser native implementations including some notion of virtual lists so the browser would not choke when rendering a lot of content.

Eventually, this would be same as border-radius. It will get implemented and we'll forget about that forever.

  • I thought the promise of Web Components was also about this: make a control once, make it styleable, let everyone reuse it.

    I wonder why is this not happening widely.

    • It's not surprising, really: web components suck for having highly-customizable inputs.

      1. You get HTML attributes to pass data in, or JavaScript properties. If you're in React, you'd just use a React component and skip web components. If you're in vanilla HTML, you can't just write HTML, you have to build the component with the DOM.

      2. There's no real standard to making web components look the way you want them to. You can't just use CSS (you have to have the shadow root "adopt" the styles). Your point of "make it styleable" is actually one of web components' biggest weaknesses (IMO).

      3. Web components are globally registered. React/Vue/Svelte/etc. components are objects that you use. You end up with a mess of making sure you registered all of the components you want before you use them (and not registering the ones you don't use) and hope no two packages you like use the same name.

    • Web components are pretty terrible, and do not work as you would expect them to. Take this, for example

          <some-element>
              <input type="text">
          </some-element>
      

      So <some-element> is a web component that adds extra features to the input. So it constructs a shadow DOM, puts the <input> into it, styles the input appropriately, etc. And before the web component finishes loading, or if it fails, or if web components aren’t supported in some way, it still works like a normal <input>.

      Now take this:

          <some-element>
              <textarea>…</textarea>
          </some-element>
      

      Same thing. You’ve got a normal <textarea>, and the web component adds its extra stuff.

      Now take this:

          <some-element>
              <select>
                  <option>…</option>
              </select>
          </some-element>
      

      Same thing, right? Nope! This doesn’t work! Web components can only style their immediate children. So the first web component can style the <input> element, the second web component can style the <textarea> element, and the third web component can style the <select> element… but it can’t style the <option> element.

      Web components are full of all of these random footguns.

    • Because web components themselves break even in the expected situations? And need 20+ new spec to make them work? And because they are neither low level enough nor high level enough to be useful for the use case you described?

- Why is picker a function like `::picker(select)`, and not a CSS pseudo class like `::before` to select the `select`'s `picker` component? I.e., `select::picker` makes a lot more sense to me.

- What about multi-choice (`multiple` attribute) `select`s?

  • Because it's been trendy to introduce a new unintuitive syntax with every new CSS feature.

    I am genuinely afraid for the future of CSS as it is becoming increasingly more complex, meanwhile most people haven't been able to properly utilize or understand it for the last decade even without all of that additional complexity.

I don’t really see if there’s now an option to further improve the select with JavaScript to add, for example, a search textbox for filtering.

And what about the nearly unusable (on desktop) <select multiple>?

  • I don’t understand the hatred for select multiple on desktop. It’s a list box that uses standard UI conventions that have been present for three or four decades now.

    • They're probably referring to it not being usable without keyboard, unlike regular select, or checkboxes, or anything else sans a text field. Specifically, to select elements one by one, you need to hold down Ctrl (on Windows; modifiers for other OSes are different).

      For better or worse, this element is not obvious for those who didn't grow up using desktop computers 10+ years ago.

    • I use it in one place in my app, and even with me putting text right above it saying something like "ctrl+click to select multiple entries", I still periodically get emails from confused users. No idea what the actual % is, but it's gotta be some non-trivial fraction of people who just have no idea how to use that thing.

They been talking about this for a long time.

In fact, I remember at some point, they were trying to sell the idea of exposing all the form inputs to use the `::part` API, since under the hood form inputs share the same general logic of custom elements, If I recall correctly.

From the looks of it, didn't work out that way though.

And I think its for the best. I like this proposal more, even though delivering the `::part` API to everyone (not just web component users) would have likely been faster

  • Using ::part() was a bad idea. Part is for user-defined pseudo elements. The platform can just define real pseudo elements. I argued against using `::part()` in spec threads, and I haven't looked back recently, but I think that argument won over.

This is a very good start, I don't think it'll replace a lot of the custom code/comboboxes that are seen in react-land without search (unless I missed it).

Wonder what is the point of this, all these functionalities are available in any third party libraries since ages.

What's the point of Chrome-only css.

  • The point of Chrome-only CSS (vendor-prefixed features) would be to allow Chrome or any other vendor to expose styling functionality to CSS authors in valid CSS syntax in ways that won't impede future standardization efforts (like writing non-standard CSS would do) or interfere with that same CSS being processed by other vendors.

    But this article isn't an example of Chrome-only CSS, this is about a change to the standard select element to make it customizeable in a standard way. It's not fully frozen yet, so they're seeking feedback and still working on it, so if you have input to give about this feature I think they'd welcome it. This blog post was about Chrome introducing experimental support for it, likely so developers can experiment with it and provide more valuable feedback towards its standardization!

  • So websites "look better in Chrome", that's what Google wants.. but it's ultimately not good for us, so I hope developers don't fall for this..

    • Why dont you read the article and see for yourself.

  • It's a middle finger to people who try to set some standards and maintain them for a while. Also, a middle finger to accessibility people.

    • It's absolutely not that- it's an early implementation of a drafted WHATWG standard in the "iteration" phase, put behind a development build and a development flag so people know that it isn't stable and might change and nobody who doesn't explicitly opt in will be affected. This is literally made to allow "people who try to set some standards" to test their proposed standards and iterate on them before finalizing the proposal.

      As far as accessibility, the native browser select is almost always going to be more accessible than someone making a custom input using JavaScript so they can add some styling control. Having the native version support basic styling is a big accessibility win IMO, because it disincentives developers from making a less accessible alternative for the sake of matching some design file.

    • The middle finger is for people like you who didnt read the first paragraph.

      > A customizable version of the select element is officially in Stage 2 in the WHATWG, with strong cross-browser interest and a prototype for you to test out from Chrome Canary 130.

Neat. Can I put an input inside the select so I can filter options?

  • > Neat. Can I put an input inside the select so I can filter options?

    How will input-inside-select be better than a datalist?

    (Genuinely curious, not being facetious)

    • An input + datalist still let you type whatever you want. What I want is a select with a finite list of options, but filterable so the user doesn't have to search manually. Specially necessary when you have lots of items and the sorting is not alphabetical.

      The select also differentiates between the value and the presentation text. With an input you would have to use the text to find the value in your db or put the value in a hidden input in the front end.

I worry this will lead to a bad user experience if android et al does not support it natively.

You'll have people saying "select the green option in the drop-down list to do <foo>" and people on mobile will just get the native-ui list with no styling.

this is a huge win for accessability.

i've re-implemented select in worse and less-accessible ways many times to satisfy some business demand. i'm very excited if this means i don't have to keep doing that.

I'm hoping that the documentation around this will be good, I've recently tried out CSS anchor positioning and it's riddled with examples that no longer work as the specification has been changed various times

Now, what’s the <https://caniuse.com/> link to this feature?

  • I think it might be this one?

    https://caniuse.com/selectlist

    The blog post says that "we're excited to see this feature progress through working groups and standards bodies" but doesn't link to anything that would help figure out which standard this ostensibly implements.

    • This is specifically not selectlist. "Previously, the Chrome team was working on the idea of a selectlist element. What's described in this post is that feature redesigned to reuse the existing select element instead."

Yeah now if they can go ahead and make ThreeJS line thickness be more than 1 that'd be greeattttt....

edit: this is a joke about "OpenGL Core Profile with the WebGL renderer" which I'm not sure if Chrome (browser) would be responsible for

  • I think you need to expand on the edit even more for this to make sense.

    • I think this change seems funny to me how late it is, front-enders at this point are used to making their own customizable drop downs. But standardization is nice I suppose. And the cross browser support thing.
