+## Usage
+
+```tsx showLineNumbers
+import {
+  Select,
+  SelectContent,
+  SelectGroup,
+  SelectItem,
+  SelectTrigger,
+  SelectValue,
+} from "@/components/ui/select"
+```
+
+```tsx showLineNumbers
+<Select>
+  <SelectTrigger className="w-[180px]">
+    <SelectValue placeholder="Theme" />
+  </SelectTrigger>
+  <SelectContent>
+    <SelectGroup>
+      <SelectItem value="light">Light</SelectItem>
+      <SelectItem value="dark">Dark</SelectItem>
+      <SelectItem value="system">System</SelectItem>
+    </SelectGroup>
+  </SelectContent>
+</Select>
+```
+
+## Composition
+
+Use the following composition to build a `Select`:
+
+```text
+Select
+├── SelectTrigger
+│   └── SelectValue
+└── SelectContent
+    ├── SelectGroup
+    │   ├── SelectLabel
+    │   ├── SelectItem
+    │   └── SelectItem
+    ├── SelectSeparator
+    └── SelectGroup
+        ├── SelectLabel
+        ├── SelectItem
+        └── SelectItem
+```
+
+## Align Item With Trigger
+
+Use the `position` prop on `SelectContent` to control alignment. When `position="item-aligned"` (default), the popup positions so the selected item appears over the trigger. When `position="popper"`, the popup aligns to the trigger edge.
+
+<ComponentPreview styleName="radix-nova" name="select-align-item" />
+
+## Groups
+
+Use `SelectGroup`, `SelectLabel`, and `SelectSeparator` to organize items.
+
+<ComponentPreview styleName="radix-nova" name="select-groups" />
+
+## Scrollable
+
+A select with many items that scrolls.
+
+<ComponentPreview styleName="radix-nova" name="select-scrollable" />
+
+## Disabled
+
+<ComponentPreview styleName="radix-nova" name="select-disabled" />
+
+## Invalid
+
+Add the `data-invalid` attribute to the `Field` component and the `aria-invalid` attribute to the `SelectTrigger` component to show an error state.
+
+```tsx showLineNumbers /data-invalid/ /aria-invalid/
+<Field data-invalid>
+  <FieldLabel>Fruit</FieldLabel>
+  <SelectTrigger aria-invalid>
+    <SelectValue />
+  </SelectTrigger>
+</Field>
+```
+
+<ComponentPreview styleName="radix-nova" name="select-invalid" />
+
+## RTL
+
+To enable RTL support in shadcn/ui, see the [RTL configuration guide](/docs/rtl).
+
+<ComponentPreview styleName="radix-nova" name="select-rtl" direction="rtl" />
