Select

Overview

The Select component provides a dropdown interface for choosing from a list of options, with support for grouping, clearing, custom indicators, and advanced rendering. Built on Base UI primitives, it offers full keyboard navigation and accessibility features out of the box.

Usage

import {
  Select,
  SelectTrigger,
  SelectValue,
  SelectContent,
  SelectItem,
  SelectGroup,
  SelectLabel,
  SelectSeparator,
  SelectClear,
  SelectIndicator,
} from "@tilt-legal/cubitt-components/primitives";

// Basic select
const fruitItems = [
  { label: "Apple", value: "apple" },
  { label: "Banana", value: "banana" },
  { label: "Cherry", value: "cherry" },
];

<Select items={fruitItems}>
  <SelectTrigger>
    <SelectValue placeholder="Select a fruit" />
  </SelectTrigger>
  <SelectContent>
    {fruitItems.map((item) => (
      <SelectItem key={item.value} value={item.value}>
        {item.label}
      </SelectItem>
    ))}
  </SelectContent>
</Select>

Pass items whenever you rely on the default <SelectValue /> output. Without that label map, the trigger can only fall back to raw values.

For complex trigger displays (icons, avatars, badges) use a render function in SelectValue for custom trigger display.

const items = [
  { label: "Alan Bold", value: "1", avatar: "https://..." },
  { label: "Nina Clark", value: "2", avatar: "https://..." },
];

<Select items={items} value={value} onValueChange={setValue}>
  <SelectTrigger>
    <SelectValue>
      {(value: string | null) => {
        const selectedItem = items.find((item) => item.value === value);
        return selectedItem ? (
          <span className="flex items-center gap-2">
            <Avatar src={selectedItem.avatar} />
            <span>{selectedItem.label}</span>
          </span>
        ) : (
          <span>Select a user</span>
        );
      }}
    </SelectValue>
  </SelectTrigger>
  <SelectContent>
    {items.map((item) => (
      <SelectItem key={item.value} value={item.value}>
        <span className="flex items-center gap-2">
          <Avatar src={item.avatar} />
          <span>{item.label}</span>
        </span>
      </SelectItem>
    ))}
  </SelectContent>
</Select>;

Using Cubitt's URL-state hooks, you can sync the select value with the URL by providing a paramName. The component automatically handles array serialization for multi-select mode.

// Single select - synced with ?category=electronics
const categoryItems = [
  { label: "Electronics", value: "electronics" },
  { label: "Books", value: "books" },
  { label: "Clothing", value: "clothing" },
];

<Select
  items={categoryItems}
  paramName="category"
  defaultValue="electronics"
>
  <SelectTrigger>
    <SelectValue placeholder="Select category" />
  </SelectTrigger>
  <SelectContent>
    {categoryItems.map((item) => (
      <SelectItem key={item.value} value={item.value}>
        {item.label}
      </SelectItem>
    ))}
  </SelectContent>
</Select>

// Multi-select - synced with ?tags=react,typescript,ui (comma-separated)
const tagItems = [
  { label: "React", value: "react" },
  { label: "TypeScript", value: "typescript" },
  { label: "UI/UX", value: "ui" },
];

<Select
  items={tagItems}
  multiple
  paramName="tags"
  defaultValue={[]}
>
  <SelectTrigger>
    <SelectValue placeholder="Select tags" />
  </SelectTrigger>
  <SelectContent>
    {tagItems.map((item) => (
      <SelectItem key={item.value} value={item.value}>
        {item.label}
      </SelectItem>
    ))}
  </SelectContent>
</Select>

// Advanced options:
<Select
  paramName="filter"
  paramClearOnDefault={true}    // Remove param when value equals default
  paramDebounce={300}           // Debounce URL updates
  onUrlValueChange={(value) => console.log("Selected:", value)}
>
  {/* ... */}
</Select>

Examples

Indicator Position

Move the selection indicator to the left side.

import {
  Select,
  SelectContent,
  SelectItem,
  SelectTrigger,
  SelectValue,
} from "@tilt-legal/cubitt-components/primitives";

const items = [
  { label: "Apple", value: "apple" },
  { label: "Banana", value: "banana" },
  { label: "Cherry", value: "cherry" },
  { label: "Orange", value: "orange" },
  { label: "Grape", value: "grape" },
];

export default function Component() {
  return (
    <Select items={items} indicatorPosition="left">
      <SelectTrigger className="w-60">
        <SelectValue placeholder="Select a fruit" />
      </SelectTrigger>
      <SelectContent>
        {items.map((item) => (
          <SelectItem key={item.value} value={item.value}>
            {item.label}
          </SelectItem>
        ))}
      </SelectContent>
    </Select>
  );
}

With Clear Button

Add a clear button to reset the selection.

import {
  SelectClear,
  SelectContent,
  SelectItem,
  SelectTrigger,
  SelectValue,
} from "@tilt-legal/cubitt-components/primitives";
import { useState } from "react";
import { Select } from "@tilt-legal/cubitt-components/primitives";

const items = [
  { label: "Apple", value: "apple" },
  { label: "Banana", value: "banana" },
  { label: "Cherry", value: "cherry" },
  // ... more items
];

export default function Component() {
  const [selectedValue, setSelectedValue] = useState<string | null>(null);

  const handleClear = () => {
    setSelectedValue(null);
  };

  const handleValueChange = (value: unknown) => {
    setSelectedValue(value as string | null);
  };

  return (
    <Select
      items={items}
      value={selectedValue}
      onValueChange={handleValueChange}
    >
      <SelectTrigger className="w-60">
        <SelectValue placeholder="Select a fruit" />
        {selectedValue && <SelectClear onClick={handleClear} />}
      </SelectTrigger>
      <SelectContent>
        {items.map((item) => (
          <SelectItem key={item.value} value={item.value}>
            {item.label}
          </SelectItem>
        ))}
      </SelectContent>
    </Select>
  );
}

With Groups

Organize related options into labeled groups with separators.

import {
  Select,
  SelectContent,
  SelectGroup,
  SelectItem,
  SelectLabel,
  SelectSeparator,
  SelectTrigger,
  SelectValue,
} from "@tilt-legal/cubitt-components/primitives";

export default function Component() {
  return (
    <Select>
      <SelectTrigger className="w-60 relative">
        <SelectValue>
          {(value) => {
            if (!value) return "Select framework...";
            const item = frameworkItems.find((item) => item.value === value);
            return item ? item.label : "Select framework...";
          }}
        </SelectValue>
      </SelectTrigger>
      <SelectContent>
        <SelectGroup>
          <SelectLabel>Frontend</SelectLabel>
          <SelectItem value="react">React</SelectItem>

          <SelectItem value="laravel">Laravel</SelectItem>
        </SelectGroup>
      </SelectContent>
    </Select>
  );
}

Destructive Item

Use the destructive variant when one option represents a dangerous choice inside an otherwise standard select list.

import {
  Select,
  SelectContent,
  SelectItem,
  SelectSeparator,
  SelectTrigger,
  SelectValue,
} from "@tilt-legal/cubitt-components/primitives";

const items = [
  { label: "Rename workspace", value: "rename" },
  { label: "Duplicate workspace", value: "duplicate" },
  { label: "Delete workspace", value: "delete" },
];

export default function Component() {
  return (
    <Select items={items}>
      <SelectTrigger className="w-60">
        <SelectValue placeholder="Choose workspace action" />
      </SelectTrigger>
      <SelectContent>
        <SelectItem value="rename">Rename workspace</SelectItem>
        <SelectItem value="duplicate">Duplicate workspace</SelectItem>
        <SelectSeparator />
        <SelectItem value="delete" variant="destructive">
          Delete workspace
        </SelectItem>
      </SelectContent>
    </Select>
  );
}

Multiple Selection

Enable multi-select mode. Labels are automatically rendered from the items prop.

import {
  Select,
  SelectContent,
  SelectItem,
  SelectTrigger,
  SelectValue,
} from "@tilt-legal/cubitt-components/primitives";

const items = [
  { label: "Apple", value: "apple" },
  { label: "Banana", value: "banana" },
  { label: "Cherry", value: "cherry" },
  // ... more items
];

export default function Component() {
  return (
    <Select items={items} defaultValue={["apple", "banana"]} multiple>
      <SelectTrigger className="w-60">
        <SelectValue placeholder="Select fruits" />
      </SelectTrigger>
      <SelectContent>
        {items.map((item) => (
          <SelectItem key={item.value} value={item.value}>
            {item.label}
          </SelectItem>
        ))}
      </SelectContent>
    </Select>
  );
}

Size Variants

The select trigger supports three size variants: sm, md (default), and lg.

  const [smValue, setSmValue] = useState<string | null>(null);
  const [mdValue, setMdValue] = useState<string | null>(null);
  const [lgValue, setLgValue] = useState<string | null>(null);

        items={items}
        value={smValue}
        onValueChange={(value) => setSmValue(value as string | null)}
      >
        <SelectTrigger size="sm" className="w-60">

          {smValue && <SelectClear onClick={() => setSmValue(null)} />}
        </SelectTrigger>
        <SelectContent>
          {items.map((item) => (

        onValueChange={(value) => setMdValue(value as string | null)}
      >
        <SelectTrigger className="w-60">
          <SelectValue placeholder="Medium" />
          {mdValue && <SelectClear onClick={() => setMdValue(null)} />}
        </SelectTrigger>

            </SelectItem>
          ))}
        </SelectContent>
      </Select>

      <Select
        items={items}
        value={lgValue}
        onValueChange={(value) => setLgValue(value as string | null)}
      >
        <SelectTrigger size="lg" className="w-60">
          <SelectValue placeholder="Large" />
          {lgValue && <SelectClear onClick={() => setLgValue(null)} />}
        </SelectTrigger>
        <SelectContent>
          {items.map((item) => (
