@presetui/primitives

Headless UI primitives from PresetUI — unstyled compound components in the spirit of Radix UI, plain JavaScript with types generated from JSDoc.

Popover · Dropdown Menu (with submenus) · Listbox (custom select) · Combobox · Tooltip · Dialog (on the native <dialog>) · Toast — plus the shared core (positioning, dismiss layers, controllable state, roving focus, typeahead, asChild prop merging).

npm install @presetui/primitives

import { Popover, PopoverContent, PopoverTrigger } from "@presetui/primitives/popover"

<Popover>
  <PopoverTrigger asChild>
    <button>Open</button>
  </PopoverTrigger>
  <PopoverContent side="bottom" className="your-styles">…</PopoverContent>
</Popover>

The contract:

• Zero styling — style via data-state, data-side, data-highlighted, data-disabled attributes.
• Every part forwards className, style, ref, and all DOM props; triggers accept asChild.
• WAI-ARIA patterns and full keyboard maps, documented in each module's header comment.
• No dependencies; React 19+ peer only.

Prefer owning the code? Every primitive is also a single copyable file: https://presetui.com/r/primitives/<name>.txt (shared core embedded). This package is built from those same files.
