feat(twake-mui): ghost chip variant by Crash-- · Pull Request #214 · linagora/twake-ui

Crash-- · 2026-10-28T10:56:00Z

Adds the ghost Chip of the Teammail 1.1 mockup, used for quick filters. At rest it is neutral on the default background. Once applied it takes its colour at action.selectedOpacity (8% in light mode, 16% in dark mode), with its label and icons in that colour, as in the Figma. Hover and focus lay the action colours over that background, and the delete icon keeps its colour on hover.

Nothing changes where the variant is not used.

Default and primary chips, light mode:

Dark mode:

Design decisions by @swanndesign25.

Summary by CodeRabbit

New Features
- Added a ghost style option for chips. Default ghost chips use primary-colored text on the default background, while colored ghost chips use the selected palette color with a translucent background.
- Ghost chips display hover and focus overlays. Colored ghost chips strengthen their translucent background in these states, and their icons—including delete icons—inherit the chip’s color.

Walkthrough

The Chip theme override now supports a ghost variant for default and colored chips, with hover and focus styling. Chip props typing accepts the variant. Storybook controls and screenshot variants include it, and the screenshot grid sizing has changed.

Change: Feature

Merge Risk: Low · up to f8aad

This adds a ghost Chip variant without changing existing chips. One small gap remains: on colored ghost chips, keyboard focus is hard to tell apart from hover when the pointer is also over the chip. An added focus outline would close it, and it is not a merge blocker.

why adding a new variant instead of overriding the colors, in the comp or in the app theme directly?

Use the hover and focus action colors for default-color soft Chips.

The Screenshot story renders reachable color="default", variant="soft", clickable Chips. The current rule uses action.selected for both states. In light mode, that is 8%, while hover is 4% and focus is 12%. Hover is too strong and focus is too weak.

Suggested fix

- [`&.${chipClasses.clickable}:hover, &.${chipClasses.focusVisible}`]: - { backgroundColor: action.selected } + [`&.${chipClasses.clickable}:hover`]: { + backgroundColor: action.hover + }, + [`&.${chipClasses.focusVisible}`]: { + backgroundColor: action.focus + }

@Crash-- ok so I talked with @swanndesign25 because, we previously decided each other to remove the "ghost" variant from Chips... so now we want it again. This is this PR. So you can rename "soft" in "ghost" and apply it "the way" we did in cozy-ui.

JF-Cozy · 2026-11-02T09:45:07Z

Use the ghost opacity tokens added in #227 (8% at rest, 16% on hover and focus, in both modes), as cozy-ui and the ghost Button do. Rebase on main once #227 is merged.

...radioColors.map(color => ({ props: { variant: 'ghost' as const, color }, style: { color: theme.vars.palette[color].main, backgroundColor: theme.alpha( theme.vars.palette[color].main, action.ghostOpacity ), [`& .${chipClasses.icon}, & .${chipClasses.deleteIcon}`]: { color: 'inherit' }, // MUI's coloured chips switch the delete icon to contrastText [`& .${chipClasses.deleteIcon}:hover, & .${chipClasses.deleteIcon}:active`]: { color: 'inherit' }, [`&.${chipClasses.clickable}:hover, &.${chipClasses.focusVisible}`]: { backgroundColor: theme.alpha( theme.vars.palette[color].main, action.hoverGhostOpacity ) } } }))

+
+// The delete icon keeps the chip colour while hovered or pressed. Synthetic
+// events do not trigger :hover, so the play reads the winning CSS rule.
+export const GhostDeleteIconHover: Story = {


Remove the GhostDeleteIconHover story and the expect import. The play function reads emotion's generated css- class and the last matching rule, so it breaks on any emotion or rule-order change, and it only asserts that a style override is written. The Screenshot story already covers the ghost rendering.

Remove this comment: it describes what the two variants below do. The other two comments (gradient over the rest colour, MUI's contrastText delete icon) explain real constraints and can stay.

The design draws quick filters as ghost chips: neutral on the default background at rest, and tinted with their colour at the ghost opacity, in that colour's text, once applied. A neutral chip lays the action colours over its rest colour on hover and focus, a coloured chip raises its tint to the hover ghost opacity.

Add a focus indicator to colored ghost chips that differs from hover.

The colored ghost variant gives keyboard focus the same background as hover. When the pointer is also over the chip, focus looks the same as hover. Add an outline for focusVisible so keyboard focus stays distinct.
