Radix Primitives

Radix Primitives is an open-source library of unstyled, low-level React components such as dialog, dropdown menu, popover, slider, tabs and accordion, built to follow the WAI-ARIA design patterns. It handles the hard parts, including focus management, keyboard navigation, typeahead, collision-aware positioning and screen-reader semantics, and leaves all styling to you. It sits underneath shadcn/ui and many design systems, which makes it the reference for how accessible interactive components should behave.
