Examples

Change the positioning mode

By default, Select will behave similarly to a native MacOS menu by positioning Select.Content relative to the active item. If you would prefer an alternative positioning approach similar to Popover or DropdownMenu then you can set position to popper and make use of additional alignment options such as side, sideOffset and more.

// index.jsx
import * as Select from '@radix-ui/react-select';
export default () => (
<Select.Root>
<Select.Trigger></Select.Trigger>
<Select.Portal>
<Select.Content position="popper" sideOffset={5}>
</Select.Content>
</Select.Portal>
</Select.Root>
);

Constrain the content size

When using position="popper" on Select.Content, you may want to constrain the width of the content so that it matches the trigger width. You may also want to constrain its height to not exceed the viewport.

We expose several CSS custom properties such as --radix-select-trigger-width and --radix-select-content-available-height to support this. Use them to constrain the content dimensions.

// index.jsx
import * as Select from '@radix-ui/react-select';
import './styles.css';
export default () => (
<Select.Root>
<Select.Trigger></Select.Trigger>
<Select.Portal>
<Select.Content className="SelectContent" position="popper" sideOffset={5} >
</Select.Content>
</Select.Portal>
</Select.Root>
);
/* styles.css */
.SelectContent {
width: var(--radix-select-trigger-width);
max-height: var(--radix-select-content-available-height);
}

With disabled items

You can add special styles to disabled items via the data-disabled attribute.

// index.jsx
import * as Select from '@radix-ui/react-select';
import './styles.css';
export default () => (
<Select.Root>
<Select.Trigger></Select.Trigger>
<Select.Portal>
<Select.Content>
<Select.Viewport>
<Select.Item className="SelectItem" disabled>
</Select.Item>
<Select.Item></Select.Item>
<Select.Item></Select.Item>
</Select.Viewport>
</Select.Content>
</Select.Portal>
</Select.Root>
);
/* styles.css */
.SelectItem[data-disabled] {
color: 'gainsboro';
}

With a placeholder

You can use the placeholder prop on Value for when the select has no value. There's also a data-placeholder attribute on Trigger to help with styling.

// index.jsx
import * as Select from '@radix-ui/react-select';
import './styles.css';
export default () => (
<Select.Root>
<Select.Trigger className="SelectTrigger">
<Select.Value placeholder="Pick an option" />
<Select.Icon />
</Select.Trigger>
<Select.Portal>
<Select.Content></Select.Content>
</Select.Portal>
</Select.Root>
);
/* styles.css */
.SelectTrigger[data-placeholder] {
color: 'gainsboro';
}

With separators

Use the Separator part to add a separator between items.

<Select.Root>
<Select.Trigger></Select.Trigger>
<Select.Portal>
<Select.Content>
<Select.Viewport>
<Select.Item></Select.Item>
<Select.Item></Select.Item>
<Select.Item></Select.Item>
<Select.Separator />
<Select.Item></Select.Item>
<Select.Item></Select.Item>
</Select.Viewport>
</Select.Content>
</Select.Portal>
</Select.Root>

With grouped items

Use the Group and Label parts to group items in a section.

<Select.Root>
<Select.Trigger></Select.Trigger>
<Select.Portal>
<Select.Content>
<Select.Viewport>
<Select.Group>
<Select.Label>Label</Select.Label>
<Select.Item></Select.Item>
<Select.Item></Select.Item>
<Select.Item></Select.Item>
</Select.Group>
</Select.Viewport>
</Select.Content>
</Select.Portal>
</Select.Root>

With complex items

You can use custom content in your items.

import * as Select from '@radix-ui/react-select';
export default () => (
<Select.Root>
<Select.Trigger></Select.Trigger>
<Select.Portal>
<Select.Content>
<Select.Viewport>
<Select.Item>
<Select.ItemText>
<img src="" />
Adolfo Hess
</Select.ItemText>
<Select.ItemIndicator></Select.ItemIndicator>
</Select.Item>
<Select.Item></Select.Item>
<Select.Item></Select.Item>
</Select.Viewport>
</Select.Content>
</Select.Portal>
</Select.Root>
);

Controlling the value displayed in the trigger

By default the trigger will automatically display the selected item ItemText's content. You can control what appears by chosing to put things inside/outside the ItemText part.

If you need more flexibility, you can control the component using value/onValueChange props and passing children to SelectValue. Remember to make sure what you put in there is accessible.

const countries = { france: '🇫🇷', 'united-kingdom': '🇬🇧', spain: '🇪🇸' };
export default () => {
const [value, setValue] = React.useState('france');
return (
<Select.Root value={value} onValueChange={setValue}>
<Select.Trigger>
<Select.Value aria-label={value}>
{countries[value]}
</Select.Value>
<Select.Icon />
</Select.Trigger>
<Select.Portal>
<Select.Content>
<Select.Viewport>
<Select.Item value="france">
<Select.ItemText>France</Select.ItemText>
<Select.ItemIndicator></Select.ItemIndicator>
</Select.Item>
<Select.Item value="united-kingdom">
<Select.ItemText>United Kingdom</Select.ItemText>
<Select.ItemIndicator></Select.ItemIndicator>
</Select.Item>
<Select.Item value="spain">
<Select.ItemText>Spain</Select.ItemText>
<Select.ItemIndicator></Select.ItemIndicator>
</Select.Item>
</Select.Viewport>
</Select.Content>
</Select.Portal>
</Select.Root>
);
};

With custom scrollbar

The native scrollbar is hidden by default as we recommend using the ScrollUpButton and ScrollDownButton parts for the best UX. If you do not want to use these parts, compose your select with our Scroll Area primitive.

// index.jsx
import * as Select from '@radix-ui/react-select';
import * as ScrollArea from '@radix-ui/react-scroll-area';
import './styles.css';
export default () => (
<Select.Root>
<Select.Trigger></Select.Trigger>
<Select.Portal>
<Select.Content>
<ScrollArea.Root className="ScrollAreaRoot" type="auto">
<Select.Viewport asChild>
<ScrollArea.Viewport className="ScrollAreaViewport">
<StyledItem></StyledItem>
<StyledItem></StyledItem>
<StyledItem></StyledItem>
</ScrollArea.Viewport>
</Select.Viewport>
<ScrollArea.Scrollbar className="ScrollAreaScrollbar" orientation="vertical" >
<ScrollArea.Thumb className="ScrollAreaThumb" />
</ScrollArea.Scrollbar>
</ScrollArea.Root>
</Select.Content>
</Select.Portal>
</Select.Root>
);
/* styles.css */
.ScrollAreaRoot {
width: 100%;
height: 100%;
}
.ScrollAreaViewport {
width: 100%;
height: 100%;
}
.ScrollAreaScrollbar {
width: 4px;
padding: 5px 2px;
}
.ScrollAreaThumb {
background: rgba(0, 0, 0, 0.3);
border-radius: 3px;
}

Accessibility

Adheres to the ListBox WAI-ARIA design pattern.

See the W3C Select-Only Combobox example for more information.

Custom APIs

Create your own API by abstracting the primitive parts into your own component.

Abstract down to Select and SelectItem

This example abstracts most of the parts.

Usage

import { Select, SelectItem } from './your-select';
export default () => (
<Select defaultValue="2">
<SelectItem value="1">Item 1</SelectItem>
<SelectItem value="2">Item 2</SelectItem>
<SelectItem value="3">Item 3</SelectItem>
</Select>
);
