Base appearance for list box select elements

[josepharhar]

What is the issue with the HTML Standard?

In the customizable select PR, we defined base appearance for the select element rendered as a drop-down box without the multiple attribute.

Next, I’d like to define base appearance for the select element when rendered as a list box, with and without the multiple attribute.

Relevant HTML issues:

• Rendering <select> as a listbox is a one-line widget that opens a popup on iOS and Android #8189

Relevant CSS issues:

• [css-forms-1] Should appearance: base-select work on listbox selects? (<select size>/<select multiple>) w3c/csswg-drafts#12468
• [selectors] Add pseudo-classes for <select> being a drop-down box vs a list box w3c/csswg-drafts#7422
• [css-forms-1] UA styles for base appearance listbox select elements w3c/csswg-drafts#12510

The CSS Working Group just discussed Base appearance for list box select elements, and agreed to the following:

The full IRC log of that discussion

<emilio> ACTION: fantasai to file issue about max-lines behavior
<masonf> jarhar: hoping UA styles would be done. But I created an HTML spec PR for base appearance.
<masonf> ...hoping straightforward. Removing special cases for only base appearance for menulist rendering.
<masonf> ...please take a look
<masonf> astearns: not a huge PR, but I haven't reviewed.
<masonf> jarhar: I also filed standards positions for this.
<masonf> astearns: any immediate feedback?
<masonf> annevk: haven't reviewed yet
<masonf> ...might take me a bit, travel, etc.

<masonf> zcorpan: I can take a look
<masonf> fantasai: one question to resolve today: whether select without size attr has a height limit or fits contents
