Multi Select

A tag-style multi-select with keyboard chips, filtering, and accessible removal — one component, tokened across themes.

Real use · pick several frameworks (string items)

Using Multi Select

Silica ships one design system through three paths. They share a class vocabulary but are not interchangeable — pick the one that matches what you are building.

Plain HTML — CSS classes

The Tailwind v4 plugin. Works in any framework or none — Rails, Django, PHP, Go, a static file. This path ships no JavaScript, so Multi Select is styled but inert: its behavior comes from combobox. For that behavior with no framework, use the node-tree path below.

/* in your CSS */
@import "tailwindcss";
@plugin "@wizeworks/silicaui";

Root class multi-select, with 19 modifiers:

  • .multi-select
  • .multi-select-accent
  • .multi-select-chip
  • .multi-select-chip-remove
  • .multi-select-chips
  • .multi-select-clear
  • .multi-select-error
  • .multi-select-info
  • .multi-select-input
  • .multi-select-lg
  • .multi-select-md
  • .multi-select-neutral
  • .multi-select-primary
  • .multi-select-secondary
  • .multi-select-sm
  • .multi-select-success
  • .multi-select-trigger
  • .multi-select-warning
  • .multi-select-xl
  • .multi-select-xs

React

Typed components over those same classes, with behavior and accessibility from Base UI.

npm i @wizeworks/silicaui-react
import { MultiSelect } from "@wizeworks/silicaui-react";

anchorBasePositionerProps["anchor"]noWhat to position against. Defaults to the component's own trigger.
positionMethodBasePositionerProps["positionMethod"]noabsolute (default) or fixed. Use fixed to escape a clipping ancestor.
alignOffsetBasePositionerProps["alignOffset"]noOffset along the alignment axis, in px. Pairs with align.
collisionBoundaryBasePositionerProps["collisionBoundary"]noThe element the popup must stay inside. Defaults to the viewport — set it to a scroll container so the popup collides with the panel, not the window.
collisionPaddingBasePositionerProps["collisionPadding"]noInset from the collision boundary, in px.
collisionAvoidanceBasePositionerProps["collisionAvoidance"]noWhich collision strategy runs per axis (flip, shift, none).
stickyBasePositionerProps["sticky"]noKeep the popup glued to the anchor while it scrolls out of view.
arrowPaddingBasePositionerProps["arrowPadding"]noMinimum distance from the popup's corner to the arrow, in px.
disableAnchorTrackingBasePositionerProps["disableAnchorTracking"]noStop re-measuring when the anchor moves. Cheaper, but goes stale.

Source of the demo above

The exact file that renders the examples above, so it can never drift from them. It imports a few of this site’s own layout helpers (../lib/…), so read it for the component calls rather than copying it whole.

Vanilla — node tree to HTML

The framework-neutral form of Multi Select. Build a node tree, project it with toHtml(), and let the zero-dependency runtime hydrate it. This is the path for generated or user-authored documents — a site builder, CMS output, a static export.

npm i @wizeworks/silicaui-html @wizeworks/silicaui-behaviors
import { atom, toHtml } from "@wizeworks/silicaui-html";

const node = atom("MultiSelect", "multi-select", { /* props */ });
const markup = toHtml(node);

Styling on this path is the class string in the second argument — the same classes as the Plain HTML section above. There is no color prop here; write "multi-select multi-select-primary" rather than passing a colour as a prop.

Load @wizeworks/silicaui-behaviors on the page or this markup renders correctly and does nothing.

The full API for Multi Select, on every path, is available through the Silica MCP server.
