Description

Accordion Spectrum 2 migration

Accordion now uses Spectrum 2 tokens and specifications. New sized tokens are used for corner rounding, the spacing around the disclosure icon, and the spacing around the content area.

A few notes on tokens: Medium top-to-text spacing tokens appear to be the wrong values (they appear to be the large values, not the values seen in the spec), I've followed up on this with design and assume that the correct values will be added later. Background color tokens also don't match the spec, I've followed up on this as well and have temporary colors that match the spec in place. Finally, so far we've noticed that the design spec appears to have a focus indicator gap but the token spec is 0 (no gap), so that is another follow-up item. The accordion-item-to-divider token is not used here per previous guidance from the designer.

New features

Adds the optional "quiet" style, which does not show dividers between accordion items.
Adds the "no inline padding" variant. This variant will be used within "standard panel".
Adds CSS transition to animate the rotation of the disclosure indicator when expanding and
collapsing the accordion item.
Per design spec, accordion items have a min-width and default width. Default width can be
overridden with --mod-accordion-item-width but should not be smaller than
--spectrum-accordion-item-minimum-width.

Markup changes

The HTML markup has changed slightly for the accordion header. The disclosure icon has been moved
from outside the the button (spectrum-Accordion-itemHeader), to within the button. The extra
element with class spectrum-Accordion-itemIconContainer, previously wrapping the icon, has
been removed. A span with class spectrum-Accordion-itemTitle has been added around the heading
text.

Mod changes

The following --mod custom properties have been renamed to better reflect how they are used:

--mod-accordion-item-height has been renamed to --mod-accordion-item-minimum-height
--mod-accordion-min-block-size has been renamed to --mod-accordion-item-min-block-size
--mod-accordion-component-edge-to-text has been renamed to --mod-accordion-content-padding-inline

New mods:

--mod-accordion-animation-duration
--mod-accordion-edge-to-content-area
--mod-accordion-item-minimum-width
--mod-accordion-top-to-disclosure-indicator

CSS-1018

Note: this does not include the new "direct actions" feature. That will be done in a follow-up PR/task.

How and where has this been tested?

Please tag yourself on the tests you've marked complete to confirm the tests have been run by someone other than the author.

Validation steps

Open the storybook for the accordion component:
- Verify the boolean Quiet Style Variant has been added. When applied it should not show dividers between accordion items.
- Verify the No Inline Padding variant has been added . When applied it should remove inline padding from the accordion.
- Verify working CSS transition that animates the rotation of the disclosure indicator when expanding and
  collapsing the accordion item
- Verify all related documentation has been added
- Verify token additions align with token spec (see notes above in the description)

Regression testing

Validate:

The documentation pages for at least two other components are still loading, including:

The pages render correctly, are accessible, and are responsive.

If components have been modified, VRTs have been run on this branch:

VRTs have been run and looked at.
Any VRT changes have been accepted (by reviewer and/or PR author), or there are no changes.

Nice work, I did some review on the documentation for a first pass! I will also take a look at the CSS and tokens but decided to put that in a separate review since those usually take a bit to validate and I already have quite a few comments in this review.

Looks like rounded corners should only be "for keyboard focus and quiet hover" but is currently always applying:

matches spec for top-to-text spacing and bottom-to-text-spacing removes now-deprecated top-to-text-regular- tokens

change rgb syntax for background colors fix: use different colors for background The `background-opacity-hover`, `background-opacity-down`, and `background-opacity-key-focus` tokens' values did not match the design spec, design has been asked and the custom properties here have been updated to match the colors in the spec with the understanding that this may be temporary. Additionally, the previous rgb syntax did not work and comma syntax was required, if we need to use opacity tokens when the correct ones become available, we will likely need to use the comma syntax instead of the slash syntax that was used previously.

Adds a :not(.is-disabled) selector for hover/focus/active states to ensure that those styles do not apply for disabled accordion item headers. In many cases this is not necessary, but when a --mod is used for hover/ focus/active colors, the mod was still being applied even when the disabled class was present.

was previously being flagged as unused. the icon's size is also set by ui-icons, but this provides a fallback for sizing as well as a mod, --mod-accordion-disclosure-indicator-height

This reverts commit cdcba08. I had initially thought this was skipped over, but after reviewing some of the previous discussion on this via Slack, it seems like it is safe not to include it, so the commit is being reverted. In addition to reverting the commit, metadata has been updated.

…led" oops This reverts commit 3372bd9.

Instead of putting the --mod variables for colors where styles are defined, --mods are now used in the custom property definition. This aligns with a couple of the other color definitions, such as --spectrum-accordion-item-content-color and --spectrum-accordion-divider-color. This also makes it so that a mod used for the background, for example, is overridden by disabled styles instead of persisting through the disabled styles.

To keep the pattern of defining custom properties for tokens consistent, this defines a custom property for the accordion-focus-indicator-gap token. It has been renamed to accordion-item-focus-indicator-gap. To keep patterns consistent, other focus-indicator custom properties have been renamed to include "item" in the name. Metadata has been updated and changeset changes have been documented.

@hover

Accordion item's background color should change on active, but it wasn't visible when it was active and hovered. Active styles should take precedence over hover styles but the @hover media query prevents this. To fix this, the specificity of the active styles was increased, similar to #3767.

- clarify language around density options - other minor documentation edits for clarity, grammar, format, and consistent class notation (`.class-name`) - use sentence case where it wasn't used - add description to hasNoInlinePadding - add migrated tags/status - move custom width story to hang out with the other docs only stories - centers accordion - because default width tokens are applied, the padded layout no longer seems necessary and looks awkward left-aligned, but we can bring this back if there are unintended side effects
