What?

Aligns Menu selection indicators and prefix icons with the first label line, with or without descriptions. Adds Menu.PrefixIcon and adopts it in Menu examples, DataViews column menus, and the editor's More menu.

Why?

Leading visuals were centered against the full label and description, placing them below the first label line.

How?

Items share a top-aligned layout and label line-height. Menu.PrefixIcon defaults to 24px and calculates its margin from that line-height and the icon size. Selection indicators use a one-label-line-high wrapper, with an additional 1px downward optical adjustment for the checkbox checkmark.

Arbitrary prefixes retain their natural height. The More menu adapter preserves support for Dashicons and custom icon components.

<Menu.Item prefix={ <Menu.PrefixIcon icon={ archive } /> }>
    <Menu.ItemLabel>Archive</Menu.ItemLabel>
    <Menu.ItemDescription>Move this item to the archive.</Menu.ItemDescription>
</Menu.Item>

Testing Instructions

1. Open Design System > Components > Menu in Storybook. Check Default, Rich Items, Checkbox Items, and Radio Items. Prefix icons, checkmarks, and dots should align with the first label line, regardless of descriptions or selection indicators.
2. Make an item label long enough to wrap. Confirm its leading visuals remain aligned with the first line. Single-line items retain their height but now use the same top-aligned layout.
3. Open a DataViews table column menu and the editor's More menu. Check icon alignment and confirm menu actions still work. Plugin-provided Dashicons and custom icon components should still render.

Testing Instructions for Keyboard

1. Focus each story trigger and press Enter to open the menu.
2. Use the arrow keys to move through items and Space to toggle checkboxes or select radio items.
3. Press Escape to close the menu and confirm focus returns to the trigger.

📝 Walkthrough

Walkthrough

The Menu package adds a public PrefixIcon component and aligns menu prefixes and selection indicators with the first label line. DataViews and Editor consumers now use the component for SVG menu icons. Stories, guidelines, tests, and changelogs cover the updated behavior.

Changes

Menu PrefixIcon

Layer / File(s)	Summary
PrefixIcon API and export packages/ui/src/menu/prefix-icon.tsx, packages/ui/src/menu/index.ts, packages/ui/src/menu/types.ts	Adds the ref-forwarding Menu.PrefixIcon component, its props alias, and the public export.
Menu prefix and indicator alignment packages/ui/src/menu/style.module.css, packages/ui/src/menu/checkbox-item.tsx, packages/ui/CHANGELOG.md	Shares the label line height and top-aligns menu content, prefixes, and indicators. Checkbox icons receive a one-pixel optical offset.
Integrated PrefixIcon usage packages/ui/src/menu/stories/index.story.tsx, packages/dataviews/src/components/dataviews-layouts/table/column-header-menu.tsx, packages/editor/src/components/more-menu/more-menu-item.tsx, packages/editor/package.json, packages/editor/tsconfig*.json	Migrates menu SVG prefixes to Menu.PrefixIcon. MoreMenuItem preserves support for Dashicon slugs and custom icons.
Validation and guidance packages/ui/src/menu/test/index.jsdom.test.tsx, packages/ui/src/menu/stories/usage-guidelines.mdx	Tests sizing, prop and ref forwarding, and accessibility behavior. Documentation describes first-line alignment and single-line centering.
Release notes packages/dataviews/CHANGELOG.md, packages/editor/CHANGELOG.md	Records the DataViews and Editor integrations and the alignment fix.

@WordPress/gutenberg-design here's a first iteration of the attempt to align checkbox, radio dot and prefix at the top:

And here's a screenshot with "debug outlines" enabled:

The outlines show that checkmark and item label have (correctly) the same line height applied, but I still feel like the checkmark could be visually aligned better by pushing it down by 1/2 px.

The prefix icon is challenging, since it could literally be any content, and therefore we can't really align it with the same precision as we do with the indicator.

Here is an attempt with rendering the prefix icons at size={20}, which is matching the same line height as the item label.

And here is an attempt at keeping size={24} but applying some negative vertical margin to align it better:

Although, if we want/need a more opinionated take on the prefix icon (eg default size + alignment), we will likely have to create a dedicated Menu.PrefixIcon component to do that.

Thoughts?

It sure would be nice if our icons were stroke-based so they could easily scale to 20x20 for contexts where they need to?

My main feedback was initially that the icons were a bit high on alignment, and you then proceed to address that in a few ways.

I think we should not break the 24px rule until we have actual stroke based icons available for this, so the ones with some negative alignment to me look the best at this point. But if there's a code complexity concern, just top aligning also feels fine to me.

An alternative: question I have relates to SVG footprint—there's already a safe area baked into the SVGs. Not in this PR, but mostly a tech question: would it be possible to ask for a 20x20px icon footprint, but asking the icon to not be scaled? In some cases the icon shape would break out of its boundaries—that would be fine in almost all cases due to the safe area and gap. So it could be an editorial choice. Too complex?

[Mamaduka]

The prefix icon is challenging, since it could literally be any content, and therefore we can't really align it with the same precision as we do with the indicator.

Yeah, this is the hard part. An icon can be our hard-crafted SVG, Dashicon or a custom SVG. Our old Icon component doesn't discriminate.

I think aiming for our icon set and Dashicons to look good will be a nice outcome; we can't control 3rd party sources.

[fcoveram]

Thanks for working fast on this @ciampo

Although, if we want/need a more opinionated take on the prefix icon (eg default size + alignment), we will likely have to create a dedicated Menu.PrefixIcon component to do that.

I agree with @jasmussen about not breaking the 24px rule. That could open the door for more impactful inconsistencies. And +1 to @Mamaduka on optimizing for what we can control over.

In that vein, I like this option.

That offset alignment in the icon results in a good horizontal center alignment.

[ciampo]

Pushed a couple of updates:

• introduced a new Menu.PrefixIcon, a dedicated component for showing icons in the menu item prefixes. It bakes in the 24 size + negative margin correction, for better out-of-the-box alignment. Consumers will still able to pass literally any react children, if they need so.
• slightly shifted checkmark icon up for better alignment

Here is how things are looking with the latest updates:

Any additional feedback?

An alternative: question I have relates to SVG footprint—there's already a safe area baked into the SVGs. Not in this PR, but mostly a tech question: would it be possible to ask for a 20x20px icon footprint, but asking the icon to not be scaled?

I think that can be done — it could be a prop on Icon component(s) that crops the icon, discarding that safe padding. Definitely something to experiment with separately!

there's already a safe area baked into the SVGs. Not in this PR, but mostly a tech question: would it be possible to ask for a 20x20px icon footprint, but asking the icon to not be scaled?

Although the number was 16px and not 20px, we discovered that there were a substantial number of icons that would be cut off using this technique (#78595). So much so that we reverted it from Button. Probably good to test again with a 20px box, if we're going to consider it again.

Edit: Sorry I guess we're talking about a "negative margin"-like alignment, not clipping. Then it should be fine.

[fcoveram]

Given francisco's and Joen's positive feedback on the design approach, @WordPress/gutenberg-components do you have any remaining technical feedback?

[Mamaduka]

@ciampo, this needs rebasing for the new Status Check jobs to unblock.

[mirka]

I was wondering because it doesn't seem to have been mentioned anywhere — are we going to do this align top treatment for all the suffix items too?
