Core building blocks for your design system
Unstyled, accessible, open source React primitives for high-quality web apps and design systems.
Dialog
With modal and non-modal modes, fine-grained focus control, accessible to screen readers.
Dropdown Menu
With submenus, checkable items, collision handling, arrow key navigation, and typeahead support.
Popover
With fine-grained focus control, collision handling, origin-aware and collision-aware animations.
Slider
Supports keyboard and touch input, step interval, multiple thumbs for value ranges, and RTL direction.
Scroll Area
Supports custom cross-browser styling while maintaining the browser's native scroll behavior.
Tabs
Supports arrow key navigation, horizontal/vertical orientation, controlled or uncontrolled.
Accordion
Supports one or multiple items open at the same time, keyboard navigation, collapse and expand animation.
Radio Group
With arrow key navigation, horizontal/vertical orientation support, controlled or uncontrolled.
Toggle Group
A set of two-state buttons that can be toggled on or off. Supports single and multiple pressed buttons.

Allows the user to toggle between checked and not checked.
World-class teams use Radix Primitives to power their products
“Radix Primitives are crucial for the Node.js website and are a significant part of Node’s Web Design System. It allows our engineers to focus on what matters and create delightful experiences for the community.”
“We’ve been able to focus on building solid user experiences on top of Radix Primitives. With UI components, there are just too many angles and rabbit holes to cover for product teams that wish to move quickly.”
Spend less time on
undifferentiated work
Save time. Ship faster.
It takes a lot of time to develop and maintain a robust set of UI components, and it's mostly undifferentiated work. Building on top of Radix components will save you time and money, so you can ship a better product faster.
Focus on your product
It’s no secret that robust UI components are tricky to build. Nailing accessibility details and complex logic sucks time away from product feature development. With Radix, you can focus on your unique engineering challenges instead.
So, you think you can build a dropdown?
We agonise over API design, performance, and accessibility so you don't need to.
Full keyboard navigation
Navigate the menu using arrow keys, Escape, and Enter hotkeys, or even via typeahead.
Modal and non-modal modes
Configure whether the dropdown menu allows or blocks outside interactions.
Supports submenus
Nest another level of fully functional submenus inside the dropdown menu.
Supports assistive technology
Implements correct semantics and behaviors, so it's accessible to people using assistive technology.
Collision and origin-aware animations
Create open and close animations that take the dropdown menu’s actual position into account.
Control alignment and collisions
Position the menu anywhere relative to the trigger, taking collisions with the screen into account.
Fully managed focus
Granularly control focus behavior when user closes the dropdown menu or focuses an outside element.
Supports checkable items
Items can be used to perform actions, as well as act as checkbox or radiobutton controls.
Accessibility out of the box
ticked, menu item
WAI-ARIA compliant
Radix Primitives follow the WAI-ARIA guidelines, implementing correct semantics and behaviors for our components.
Keyboard navigation
Primitives provide full keyboard support for components where users expect to use a keyboard or other input devices.
Focus management
Out of the box, Primitives provide sensible focus management defaults, which can be further customized in your code.
Screen reader tested
We test Primitives with common assistive technologies, looking out for practical issues that people may experience.
Develop with an open, thought‑out API
One of our main goals is to provide the best possible developer experience. Radix Primitives provides a fully-typed API. All components share a similar API, creating a consistent and predictable experience.
Unstyled
No need to override styles, no specificity wars.
Composable
Granular access to each component part.
Customizable
Configure behavior, control focus, add event listeners.
Consistent
Components with similar functionality share similar API.
// Add styles with your preferred CSS technology
const TooltipContent = styled(Tooltip.Content, {
backgroundColor: 'black',
borderRadius: '3px',
padding: '5px'
});
const PopoverContent = styled(Popover.Content, {
backgroundColor: 'white',
boxShadow: '0 2px 10px -3px rgb(0 0 0 / 20%)',
borderRadius: '3px',
});
const DialogContent = styled(Dialog.Content, {
backgroundColor: 'white',
boxShadow: '0 3px 15px -4px rgb(0 0 0 / 30%)',
borderRadius: '5px',
});
// Compose a custom Tooltip component
export const StatusTooltip = ({ state, label }) => {
return (
<Tooltip.Root>
<Tooltip.Trigger asChild>
<Text>
<Status variant={state} />
</Text>
</Tooltip.Trigger>
<Tooltip.Portal>
<TooltipContent>
<Tooltip.Arrow />
{label}
</TooltipContent>
</Tooltip.Portal>
</Tooltip.Root>
);
};
// Compose a Popover with custom focus and positioning
export const StatusPopover = ({ children }) => {
const popoverCloseButton = React.useRef(null);
return (
<Popover.Root>
<Popover.Trigger>View status</Popover.Trigger>
<Popover.Portal>
<PopoverContent
align="start"
collisionPadding={10}
onOpenAutoFocus={(event) => {
// Focus the close button when popover opens
popoverCloseButton.current?.focus();
event.preventDefault();
}}
>
{children}
<Popover.Close ref={popoverCloseButton}>
Close
</Popover.Close>
</PopoverContent>
</Popover.Portal>
</Popover.Root>
);
};
// Compose a Dialog with custom focus management
export const InfoDialog = ({ children }) => {
const dialogCloseButton = React.useRef(null);
return (
<Dialog.Root>
<Dialog.Trigger>View details</Dialog.Trigger>
<Dialog.Overlay />
<Dialog.Portal>
<DialogContent
onOpenAutoFocus={(event) => {
// Focus the close button when dialog opens
dialogCloseButton.current?.focus();
event.preventDefault();
}}
>
{children}
<Dialog.Close ref={dialogCloseButton}>
Close
</Dialog.Close>
</DialogContent>
</Dialog.Portal>
</Dialog.Root>
);
};Incremental adoption
Each component is its own independently versioned package, so new components can be added alongside your existing code. No need to disrupt feature work with a huge rewrite—you can start small and add more components one by one.
Detailed docs and TypeScript support
Radix documentation contains real-world examples, extensive API references, accessibility details, and full TypeScript support. All components share a similar API, creating a consistent developer experience. You will love working with Radix Primitives.
