</button>
</DropdownMenu.Trigger>
<DropdownMenu.Portal>
<DropdownMenu.Content className="bg-white rounded-lg shadow-lg p-1 min-w-[180px]" sideOffset={5}>

<Tabs.Root defaultValue="overview">
<Tabs.List className="flex border-b">
<Tabs.Trigger value="overview" className="px-4 py-2 data-[state=active]:border-b-2 data-[state=active]:border-blue-500">

</Tabs.Trigger>
<Tabs.Trigger value="analytics" className="px-4 py-2 data-[state=active]:border-b-2 data-[state=active]:border-blue-500">

</Tabs.Trigger>
</Tabs.List>
<Tabs.Content value="overview"><OverviewPanel /></Tabs.Content>
<Tabs.Content value="analytics"><AnalyticsPanel /></Tabs.Content>

Guidelines
- Radix is unstyled — bring your own CSS/Tailwind. For pre-styled, use shadcn/ui.
asChildmerges Radix behavior onto your custom elements (no extra DOM wrappers).data-[state=active]anddata-[state=open]for styling based on component state.- Install individual packages:
@radix-ui/react-dialog,@radix-ui/react-dropdown-menu. - All components handle keyboard (Escape, Arrow keys, Enter) and screen readers automatically.
