Summary

Fixes #3078. On narrow viewports the grid suggestion menu (the /emoji picker) is wider than the screen; the right-hand columns are cut off and the menu only scrolls vertically, so those emoji cannot be reached.

Rationale

GridSuggestionMenuController already uses floating-ui's size middleware to cap the menu's height to availableHeight, but never caps its width, and the grid containers only allow vertical overflow. Capping the width the same way and allowing horizontal scrolling keeps every column reachable on any screen, and changes nothing on wide viewports where availableWidth exceeds the menu's natural width.

Changes

  • packages/react/src/components/SuggestionMenu/GridSuggestionMenu/GridSuggestionMenuController.tsx: the size middleware now also sets maxWidth from availableWidth.
  • packages/mantine/src/blocknoteStyles.css and packages/ariakit/src/style.css: the grid suggestion menu inherits max-width and gets overflow-x: auto, mirroring the existing max-height / overflow-y handling.
  • packages/shadcn/src/suggestionMenu/gridSuggestionMenu/GridSuggestionMenu.tsx: the same through the Tailwind classes (max-w-[inherit] overflow-x-auto instead of overflow-x-hidden).

Impact

Wide viewports are unaffected. On narrow viewports the menu is at most the available width and scrolls horizontally when the columns do not fit. Reducing the column count on narrow screens (the other option in the issue) is left for a follow-up, since the column count is a prop that apps configure.

Testing

There is no automated coverage for floating-ui positioning in this package, so this PR is covered by lint and type checks only (vp lint src on the touched packages). I could not verify the change on a device myself; a look at the minimal example at 320px before merging would be appreciated.

Checklist

  • Code follows the project's coding standards.
  • Unit tests covering the new feature have been added (none exist for menu positioning).
  • All existing tests pass.
  • The documentation has been updated to reflect the new feature (not needed).

Summary by CodeRabbit

  • Bug Fixes
    • Improved grid suggestion menus by constraining their width to the available screen space, including horizontal padding.
    • Added horizontal scrolling for wide suggestion-menu content, helping longer lists remain accessible without disrupting the surrounding layout.
    • Applied consistent sizing and overflow behavior across supported editor themes and styling variants.

The emoji picker is rendered as a fixed number of columns, so on narrow
viewports it was wider than the screen: the right-hand columns were cut off
and the menu only scrolled vertically. Cap the floating element's width to
the space floating-ui reports as available, the same way its height is
already capped, and let the grid scroll horizontally when the columns do
not fit.

📝 Walkthrough

Walkthrough

The grid suggestion menu now applies the available viewport width and supports horizontal scrolling in Ariakit, Mantine, and ShadCN styles.

Changes

Responsive grid suggestion menu

Layer / File(s) Summary
Floating menu width constraints
packages/react/src/components/SuggestionMenu/GridSuggestionMenu/GridSuggestionMenuController.tsx
The floating menu applies availableWidth as its maximum width.
Framework overflow styling
packages/ariakit/src/style.css, packages/mantine/src/blocknoteStyles.css, packages/shadcn/src/suggestionMenu/gridSuggestionMenu/GridSuggestionMenu.tsx
The grid suggestion menu uses border-box sizing, inherits its maximum width, and enables horizontal scrolling. ShadCN removes the minimum width and replaces horizontal overflow clipping with scrolling.

Severity of issue fixed: Medium

Merge Risk: ⚪ Minimal · up to f8969

This change caps the emoji/grid suggestion menu's width to the available viewport space and adds horizontal scrolling so all columns stay reachable on narrow screens, without altering behavior on wide viewports. Repository inspection found the width, sizing, and scrolling rules applied consistently across the Ariakit, Mantine, and ShadCN implementations, so this looks safe to merge.

A rabbit found a narrow screen,
And made the picker fit between.
Width now bends to space in sight,
Columns scroll from left to right.
Small boxes hop with borders neat,
Every emoji stays complete.

add box-border so the menu can shrink below 8rem while keeping padding within
Floating UI’s max-width. Add a regression test covering a rendered menu width
below 8rem.

With max-width capped to the available width, content-box sizing let the
padding push the menu past the cap, and the shadcn min-w-32 kept it from
shrinking on very narrow viewports.
