Usage

import { Button } from "@zenoxai/ui/components/button"
import {
  DropdownMenu,
  DropdownMenuContent,
  DropdownMenuItem,
  DropdownMenuSeparator,
  DropdownMenuTrigger,
} from "@zenoxai/ui/components/dropdown-menu"

<DropdownMenu>
  <DropdownMenuTrigger render={<Button variant="outline" />}>
    Actions
  </DropdownMenuTrigger>
  <DropdownMenuContent>
    <DropdownMenuItem onClick={viewDetails}>View details</DropdownMenuItem>
    <DropdownMenuItem onClick={assign}>Assign to me</DropdownMenuItem>
    <DropdownMenuSeparator />
    <DropdownMenuItem variant="destructive" onClick={remove}>
      Delete alert
    </DropdownMenuItem>
  </DropdownMenuContent>
</DropdownMenu>

Use a dropdown menu to group actions behind one button: the actions of a table row, the settings of a tenant, export options. Items run on click and the menu closes.

Need	Use
The same actions on right-click, as a shortcut	Context Menu
A row of menus at the top of an editor or app (“Report”, “Edit”, “View”)	Menubar
A value for a form field	Select or Combobox
A searchable list of many commands	Command
Controls other than items (inputs, sliders)	Popover

DropdownMenuContent opens below the trigger, aligned to its start edge, and is as wide as the trigger with a minimum of 9rem. Set a width with className (w-52) when the trigger is narrow, as with an icon button. Put the destructive item last, after a separator.

Examples

Groups and labels

Separate related items with DropdownMenuSeparator and head each group with a DropdownMenuLabel. A disabled item stays visible, so the user learns the action exists.

<DropdownMenu>
  <DropdownMenuTrigger render={<Button variant="outline" />}>
    Acme Corp
  </DropdownMenuTrigger>
  <DropdownMenuContent className="w-56">
    <DropdownMenuGroup>
      <DropdownMenuLabel>Tenant</DropdownMenuLabel>
      <DropdownMenuItem>Settings</DropdownMenuItem>
      <DropdownMenuItem>Users and roles</DropdownMenuItem>
      <DropdownMenuItem>Billing</DropdownMenuItem>
    </DropdownMenuGroup>
    <DropdownMenuSeparator />
    <DropdownMenuGroup>
      <DropdownMenuLabel>Data</DropdownMenuLabel>
      <DropdownMenuItem>Integrations</DropdownMenuItem>
      <DropdownMenuItem disabled>Data retention</DropdownMenuItem>
    </DropdownMenuGroup>
  </DropdownMenuContent>
</DropdownMenu>

Checkbox items

DropdownMenuCheckboxItem toggles a setting and keeps the menu open, so the user can change several in a row. Control it with checked and onCheckedChange.

function DropdownMenuCheckboxes() {
  const [columns, setColumns] = React.useState({
    severity: true,
    asset: true,
    tenant: false,
    assignee: true,
  })

  return (
    <DropdownMenu>
      <DropdownMenuTrigger render={<Button variant="outline" />}>
        Columns
      </DropdownMenuTrigger>
      <DropdownMenuContent className="w-48">
        <DropdownMenuLabel>Show columns</DropdownMenuLabel>
        {(
          [
            ["severity", "Severity"],
            ["asset", "Asset"],
            ["tenant", "Tenant"],
            ["assignee", "Assignee"],
          ] as const
        ).map(([key, label]) => (
          <DropdownMenuCheckboxItem
            key={key}
            checked={columns[key]}
            onCheckedChange={(checked) =>
              setColumns((current) => ({ ...current, [key]: checked }))
            }
          >
            {label}
          </DropdownMenuCheckboxItem>
        ))}
      </DropdownMenuContent>
    </DropdownMenu>
  )
}

Radio items

DropdownMenuRadioGroup holds a single choice, such as the sort order of a list. Control it with value and onValueChange.

function DropdownMenuRadio() {
  const [sort, setSort] = React.useState("severity")

  return (
    <DropdownMenu>
      <DropdownMenuTrigger render={<Button variant="outline" />}>
        Sort alerts
      </DropdownMenuTrigger>
      <DropdownMenuContent className="w-48">
        <DropdownMenuLabel>Sort by</DropdownMenuLabel>
        <DropdownMenuRadioGroup value={sort} onValueChange={setSort}>
          <DropdownMenuRadioItem value="severity">
            Severity
          </DropdownMenuRadioItem>
          <DropdownMenuRadioItem value="newest">
            Newest first
          </DropdownMenuRadioItem>
          <DropdownMenuRadioItem value="oldest">
            Oldest first
          </DropdownMenuRadioItem>
        </DropdownMenuRadioGroup>
      </DropdownMenuContent>
    </DropdownMenu>
  )
}

Submenu

DropdownMenuSub nests a menu that opens to the side on hover, click or the right arrow key. Keep to one level.

<DropdownMenu>
  <DropdownMenuTrigger render={<Button variant="outline" />}>
    Export
  </DropdownMenuTrigger>
  <DropdownMenuContent className="w-48">
    <DropdownMenuItem>Current page</DropdownMenuItem>
    <DropdownMenuItem>All 1,284 alerts</DropdownMenuItem>
    <DropdownMenuSeparator />
    <DropdownMenuSub>
      <DropdownMenuSubTrigger>Format</DropdownMenuSubTrigger>
      <DropdownMenuSubContent>
        <DropdownMenuItem>CSV</DropdownMenuItem>
        <DropdownMenuItem>JSON</DropdownMenuItem>
        <DropdownMenuItem>PDF report</DropdownMenuItem>
      </DropdownMenuSubContent>
    </DropdownMenuSub>
  </DropdownMenuContent>
</DropdownMenu>

Accessibility

The trigger has aria-haspopup and aria-expanded. Enter, Space and the arrow keys open the menu; arrow keys move between items, typing a letter jumps to the matching item, and Escape closes the menu and returns focus to the trigger.
An icon-only trigger needs an aria-label that names the menu (“Alert actions”).
DropdownMenuShortcut only displays the shortcut. Bind the key yourself.
DropdownMenuLabel is a visual heading and is not announced as the group’s name.

API reference

Generated from the TypeScript source. className, style and children are accepted everywhere and omitted below.

DropdownMenu

DropdownMenu is a list of actions or options opened from a button: the actions of a row, a user menu, a "More" overflow. To pick a form value, use Select; for a searchable list of commands, Command.

Prop	Type	Default
`actionsRef`	`RefObject<MenuRootActions \| null>` A ref to imperative actions. - `unmount`: Ends the closing phase of the menu after an externally controlled closing animation finishes. Call `preventUnmountOnClose()` in `onOpenChange` first, otherwise the menu completes closing on its own. Whether it leaves the DOM is decided by `keepMounted` on the portal. - `close`: Closes the menu imperatively when called.	-
`closeParentOnEsc`	`boolean` When in a submenu, determines whether pressing the Escape key closes the entire menu, or only the current child menu.	`false`
`defaultOpen`	`boolean` Whether the menu is initially open.	`false`
`defaultTriggerId`	`string \| null` ID of the trigger that the menu is associated with. This is useful in conjunction with the `defaultOpen` prop to create an initially open menu.	-
`disabled`	`boolean` Whether the component should ignore user interaction.	`false`
`handle`	`MenuHandle<unknown>` A handle to associate the menu with a trigger. If specified, allows external triggers to control the menu's open state.	-
`highlightItemOnHover`	`boolean` Whether moving the pointer over items should highlight them. Disabling this prop allows CSS `:hover` to be differentiated from the `:focus` (`data-highlighted`) state.	`true`
`loopFocus`	`boolean` Whether to loop keyboard focus back to the first item when the end of the list is reached while using the arrow keys.	`true`
`modal`	`boolean` Determines if the menu enters a modal state when open. - `true`: user interaction is limited to the menu: document page scroll is locked and pointer interactions on outside elements are disabled. - `false`: user interaction with the rest of the document is allowed.	`true`
`onItemHighlighted`	`((highlightedItem: HTMLElement, eventDetails: MenuRootHighlightEventDetails) => void)` Callback fired when an item is highlighted or unhighlighted. Receives the highlighted item element (or `undefined` if no item is highlighted) and details containing the reason for the change, the event, and the item's text label. The `reason` can be: - `'keyboard'`: the highlight changed due to keyboard navigation. - `'pointer'`: the highlight changed due to pointer hovering. The event may be a `MouseEvent` rather than a `PointerEvent`. - `'none'`: the highlight changed for another reason, such as automatic highlighting while filtering, the item list changing, or the popup opening or closing.	-
`onOpenChange`	`((open: boolean, eventDetails: MenuRootChangeEventDetails) => void)` Event handler called when the menu is opened or closed.	-
`onOpenChangeComplete`	`((open: boolean) => void)` Event handler called after any animations complete when the menu is opened or closed.	-
`open`	`boolean` Whether the menu is currently open.	-
`orientation`	`"horizontal" \| "vertical"` The visual orientation of the menu. Controls whether roving focus uses up/down or left/right arrow keys.	`'vertical'`
`triggerId`	`string \| null` ID of the trigger that the menu is associated with. This is useful in conjunction with the `open` prop to create a controlled menu. There's no need to specify this prop when the menu is uncontrolled (that is, when the `open` prop is not set).	-

DropdownMenuPortal

DropdownMenuPortal moves the menu to the end of the document body. DropdownMenuContent renders it already.

Prop	Type	Default
`container`	`HTMLElement \| ShadowRoot \| RefObject<HTMLElement \| ShadowRoot \| null> \| null` A parent element to render the portal element into.	-
`keepMounted`	`boolean` Whether to keep the portal mounted in the DOM while the popup is hidden.	`false`
`render`	`ReactElement<unknown, string \| JSXElementConstructor<any>> \| ComponentRenderFn<HTMLProps, MenuPortalState>` Allows you to replace the component's HTML element with a different tag, or compose it with another component.	-

DropdownMenuTrigger

Prop	Type	Default
`closeDelay`	`number` How long to wait before closing the menu that was opened on hover. Specified in milliseconds.	`0`
`delay`	`number` How long to wait before the menu may be opened on hover. Specified in milliseconds.	`100`
`disabled`	`boolean` Whether the component should ignore user interaction.	`false`
`handle`	`MenuHandle<unknown>` A handle to associate the trigger with a menu.	-
`nativeButton`	`boolean` Whether the component renders a native `<button>` element when replacing it via the `render` prop. Set to `false` if the rendered element is not a button (for example, `<div>`).	`true`
`openOnHover`	`boolean` Whether the menu should also open when the trigger is hovered.	-
`payload`	`unknown` A payload to pass to the menu when it is opened.	-
`render`	`ReactElement<unknown, string \| JSXElementConstructor<any>> \| ComponentRenderFn<HTMLProps, MenuTriggerState>` Allows you to replace the component's HTML element with a different tag, or compose it with another component.	-

DropdownMenuContent

DropdownMenuContent is the menu popup, in a portal below the trigger, as wide as the trigger and at least 144px.

Prop	Type	Default
`align`	`"center" \| "start" \| "end"` How to align the popup relative to the specified side.	`start`
`alignOffset`	`number \| OffsetFunction` 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.	`0`
`finalFocus`	`boolean \| RefObject<HTMLElement \| null> \| ((closeType: InteractionType) => boolean \| void \| HTMLElement \| null)` Determines the element to focus when the menu is closed.	-
`id`	`string` @ignore	-
`render`	`ReactElement<unknown, string \| JSXElementConstructor<any>> \| ComponentRenderFn<HTMLProps, MenuPopupState>` Allows you to replace the component's HTML element with a different tag, or compose it with another component.	-
`side`	`"left" \| "right" \| "top" \| "bottom" \| "inline-end" \| "inline-start"` Which side of the anchor element to align the popup against. May automatically change to avoid collisions.	`bottom`
`sideOffset`	`number \| OffsetFunction` Distance between the anchor and the popup in pixels. Also accepts a function that returns the distance to read the dimensions of the anchor and positioner elements, along with its side and alignment.	`0`

DropdownMenuGroup

Prop	Type	Default
`render`	`ReactElement<unknown, string \| JSXElementConstructor<any>> \| ComponentRenderFn<HTMLProps, MenuGroupState>` Allows you to replace the component's HTML element with a different tag, or compose it with another component.	-

DropdownMenuLabel

DropdownMenuLabel is a section heading inside the menu. It is a plain div, not linked to the items under it, because Base UI's GroupLabel throws outside a Group. When the items need that aria-labelledby association, wrap them in a DropdownMenuGroup with `Menu.GroupLabel` from "@base-ui/react/menu".
