Select

A form control for choosing a predefined value from a dropdown list

import { Select } from "@nyte-ai/ui/select";

A trigger that opens a list of options and writes the chosen one back into a form. No Nyte styling here.

Usage

Select has no filtering beyond typeahead, which highlights the item matching what you type. For a searchable list use Autocomplete.
Give the control an accessible name with Select.Label, or an aria-label on Select.Trigger when no visible label is rendered.
name on the root submits the value through a hidden input. required, readOnly, and disabled behave like native form attributes.
Select.Value renders the raw value. Pass items to the root to render the matching label instead, or pass a function child to Select.Value to format it.
placeholder on Select.Value shows while nothing is selected. To let the user clear the value, render an item whose value is null.
multiple on the root turns value into an array.
Select.Positioner overlaps the trigger by default so the selected item's text lines up with the trigger's value text. data-side is "none" while that mode is active, and side and align are ignored. Set alignItemWithTrigger={false} to position the popup like any other dropdown.
That overlap mode is skipped for touch input, and falls back to normal positioning when the viewport is too short. A smaller min-height on the positioner falls back less often.

Examples

Theme

const themes = [
  { value: "system", label: "System default" },
  { value: "light", label: "Light" },
  { value: "dark", label: "Dark" },
];

<Select.Root items={themes} defaultValue="system">
  <div>
    <Select.Label>Theme</Select.Label>
    <Select.Trigger>
      <Select.Value />
      <Select.Icon>
        <IconChevronGrabberVertical size={12} />
      </Select.Icon>
    </Select.Trigger>
  </div>
  <Select.Portal>
    <Select.Positioner>
      <Select.Popup>
        <Select.List>
          {themes.map((theme) => (
            <Select.Item key={theme.value} value={theme.value}>
              <Select.ItemText>{theme.label}</Select.ItemText>
              <Select.ItemIndicator>
                <IconCheckmark1Small size={12} />
              </Select.ItemIndicator>
            </Select.Item>
          ))}
        </Select.List>
      </Select.Popup>
    </Select.Positioner>
  </Select.Portal>
</Select.Root>;

<Select.Value>{(value: string | null) => labels[value ?? "none"]}</Select.Value>

Pass value with onValueChange to control the selection. The handler receives null when the user picks an item whose value is null.

const [theme, setTheme] = useState("system");

<Select.Root
  items={themes}
  value={theme}
  onValueChange={(value) => {
    if (value !== null) setTheme(value);
  }}
>
  {/* Trigger and popup as above */}
</Select.Root>;

Group the items by nesting them in objects that carry an items array. Select.Value still resolves the label of the selected item. The heading text is a property you render yourself.

const groups = [
  { label: "Light", items: [{ value: "paper", label: "Paper" }] },
  { label: "Dark", items: [{ value: "night", label: "Night" }] },
];

<Select.Root items={groups} defaultValue="paper">
  {/* Trigger as above */}
  <Select.Portal>
    <Select.Positioner>
      <Select.Popup>
        <Select.List>
          {groups.map((group) => (
            <Select.Group key={group.label}>
              <Select.GroupLabel>{group.label}</Select.GroupLabel>
              {group.items.map((theme) => (
                <Select.Item key={theme.value} value={theme.value}>
                  <Select.ItemText>{theme.label}</Select.ItemText>
                </Select.Item>
              ))}
            </Select.Group>
          ))}
        </Select.List>
      </Select.Popup>
    </Select.Positioner>
  </Select.Portal>
</Select.Root>;

Props

The part tables below come from Base UI, MIT, © Material-UI SAS.

Root

Groups all parts of the select. Doesn't render its own HTML element.

Root Props:

Prop	Type	Default	Description
name	`string`	-	Identifies the field when a form is submitted.
defaultValue	`Value[] \| Value \| null`	-	The uncontrolled value of the select when it's initially rendered. To render a controlled select, use the `value` prop instead.
value	`Value[] \| Value \| null`	-	The value of the select. Use when controlled.
onValueChange	`((value: Value[] \| Value \| null, eventDetails: Select.Root.ChangeEventDetails) => void)`	-	Event handler called when the value of the select changes.
defaultOpen	`boolean`	`false`	Whether the select popup is initially open. To render a controlled select popup, use the `open` prop instead.
open	`boolean`	-	Whether the select popup is currently open.
onOpenChange	`((open: boolean, eventDetails: Select.Root.ChangeEventDetails) => void)`	-	Event handler called when the select popup is opened or closed.
highlightItemOnHover	`boolean`	`true`	Whether moving the pointer over items should highlight them. Disabling this prop allows CSS `:hover` to be differentiated from the `:focus` (`data-highlighted`) state.
actionsRef	`React.RefObject<Select.Root.Actions \| null>`	-	A ref to imperative actions. `unmount`: Manually unmounts the select. Call this after any externally controlled closing animation finishes.
autoComplete	`string`	-	Provides a hint to the browser for autofill.
form	`string`	-	Identifies the form that owns the hidden input. Useful when the select is rendered outside the form.
isItemEqualToValue	`((itemValue: Value, value: Value) => boolean)`	-	Custom comparison logic used to determine if a select item value matches the current selected value. Useful when item values are objects without matching referentially. Defaults to `Object.is` comparison.
itemToStringLabel	`((itemValue: Value) => string)`	-	When the item values are objects (`<Select.Item value={object}>`), this function converts the object value to a string representation for display in the trigger. If the shape of the object is `{ value, label }`, the label will be used automatically without needing to specify this prop.
itemToStringValue	`((itemValue: Value) => string)`	-	When the item values are objects (`<Select.Item value={object}>`), this function converts the object value to a string representation for form submission. If the shape of the object is `{ value, label }`, the value will be used automatically without needing to specify this prop.
items	`Record<string, React.ReactNode> \| ({ label: React.ReactNode; value: any })[] \| Group[]`	-	Data structure of the items rendered in the select popup. When specified, `<Select.Value>` renders the label of the selected item instead of the raw value.
modal	`boolean`	`true`	Determines if the select enters a modal state when open. `true`: user interaction is limited to the select: document page scroll is locked and pointer interactions on outside elements are disabled.`false`: user interaction with the rest of the document is allowed. On touch devices, a `true` modal blocks outside taps but leaves the page scrollable unless the popup spans nearly the full viewport width, matching native iOS behavior.
multiple	`boolean`	`false`	Whether multiple items can be selected.
onOpenChangeComplete	`((open: boolean) => void)`	-	Event handler called after any animations complete when the select popup is opened or closed.
disabled	`boolean`	`false`	Whether the component should ignore user interaction.
readOnly	`boolean`	`false`	Whether the user should be unable to choose a different option from the select popup.
required	`boolean`	`false`	Whether the user must choose a value before submitting a form.
inputRef	`React.Ref<HTMLInputElement>`	-	A ref to access the hidden input element.
id	`string`	-	The id of the Select.
children	`React.ReactNode`	-	-

items Prop Example:

const items = {
  sans: 'Sans-serif',
  serif: 'Serif',
  mono: 'Monospace',
  cursive: 'Cursive',
};
<Select.Root items={items} />;

alignOffset	`number \| OffsetFunction`	`0`	Additional offset along the alignment axis in pixels. Also accepts a function that returns the offset to read the dimensions of the anchor and positioner elements, along with its side and alignment. The function takes a `data` object parameter with the following properties: `data.anchor`: the dimensions of the anchor element with properties `width` and `height`.`data.positioner`: the dimensions of the positioner element with properties `width` and `height`.`data.side`: which side of the anchor element the positioner is aligned against.`data.align`: how the positioner is aligned relative to the specified side.
side	`Side`	`'bottom'`	Which side of the anchor element to align the popup against. May automatically change to avoid collisions.
sideOffset	`number \| OffsetFunction`	`0`	Distance between the anchor and the popup in pixels.

anchor	`Element \| VirtualElement \| React.RefObject<Element \| null> \| (() => Element \| VirtualElement \| null) \| null`	-	An element to position the popup against. By default, the popup will be positioned against the trigger.
collisionAvoidance	`CollisionAvoidance`	-	Determines how to handle collisions when positioning the popup. `side` controls overflow on the preferred placement axis (`top`/`bottom` or `left`/`right`): `'flip'`: keep the requested side when it fits; otherwise try the opposite side (`top` and `bottom`, or `left` and `right`).`'shift'`: never change side; keep the requested side and move the popup within the clipping boundary so it stays visible.`'none'`: do not correct side-axis overflow. `align` controls overflow on the alignment axis (`start`/`center`/`end`): `'flip'`: keep side, but swap `start` and `end` when the requested alignment overflows.`'shift'`: keep side and requested alignment, then nudge the popup along the alignment axis to fit.`'none'`: do not correct alignment-axis overflow. `fallbackAxisSide` controls fallback behavior on the perpendicular axis when the preferred axis cannot fit: `'start'`: allow perpendicular fallback and try the logical start side first (`top` before `bottom`, or `left` before `right` in LTR).`'end'`: allow perpendicular fallback and try the logical end side first (`bottom` before `top`, or `right` before `left` in LTR).`'none'`: do not fallback to the perpendicular axis. When `side` is `'shift'`, explicitly setting `align` only supports `'shift'` or `'none'`. If `align` is omitted, it defaults to `'flip'`.
collisionBoundary	`Boundary`	`'clipping-ancestors'`	An element or a rectangle that delimits the area that the popup is confined to.
collisionPadding	`Padding`	`5`	Additional space to maintain from the edge of the collision boundary.
