API reference

PropTypeDefaultDescription

DropdownMenuContentReact.ComponentProps<typeof DropdownMenuPrimitive.Content> & VariantProps<typeof dropDownVariants>—Accepts the Radix Content props and the font variant. `font` is `"normal"` or `"retro"`; omitted or null values render with the retro class. Also adds `mt-1 py-2` and decorative pixel-frame borders.

DropdownMenuSubContentReact.ComponentProps<typeof ShadcnDropdownMenuSubContent> & VariantProps<typeof dropDownVariants>—Accepts the underlying submenu content props and the same `font` variant as DropdownMenuContent. Omitted or null font values render with the retro class; the wrapper adds a popover background and decorative pixel-frame borders.

font"normal" | "retro" | null—Variant available on DropdownMenuContent and DropdownMenuSubContent. `"normal"` omits the retro font class; `"retro"`, null, or an omitted value applies it.

DropdownMenuItemReact.ComponentProps<typeof DropdownMenuPrimitive.Item> & { inset?: boolean; variant?: "default" | "destructive" }—Accepts the Radix Item props, plus `inset` and `variant`. These values are forwarded to the underlying shadcn item; this wrapper itself adds dashed hover and focus borders.

DropdownMenuSubTriggerReact.ComponentProps<typeof DropdownMenuPrimitive.DropdownMenuSubTrigger>—Accepts the Radix submenu trigger props and children; adds dashed hover, focus, and open-state borders.

DropdownMenu, DropdownMenuPortal, DropdownMenuTrigger, DropdownMenuGroup, DropdownMenuLabel, DropdownMenuSeparator, DropdownMenuShortcut, DropdownMenuSub, DropdownMenuCheckboxItemUnderlying shadcn component props—These exports are direct aliases of the corresponding shadcn dropdown-menu components and add no wrapper-specific props.
