Shadcn Autocomplete: Suggestion Driven Text Input for React
An autocomplete narrows a long list of options as the user types, turning a free text field into fast, forgiving selection. This react autocomplete component follows shadcn/ui conventions, is styled with Tailwind CSS, and ships as TypeScript source you can adapt to any form in a Next.js or Vite app.
Below you will find copy-paste autocomplete examples covering the everyday cases: a clear button for resetting the field, grouped options with labels, async items loading for remote data, and a variant that auto highlights the first option so Enter always selects something sensible.
What is the Shadcn Autocomplete component?
Unlike a plain select, an autocomplete keeps the input editable and filters suggestions live, which makes it the right control once a list grows past a dozen entries. Think country pickers, user search, or tag entry. The pattern combines a text input with a filtered listbox and full keyboard support.
The variants here follow the same anatomy popularized by cmdk, the filtering command list used across the shadcn ecosystem, so the API will feel familiar if you have used a command palette before.
Why use this autocomplete?
- Typeahead speed: Users find an option in a few keystrokes instead of scrolling a long dropdown, which matters for lists like countries, users, or products.
- Async ready: The async items loading example shows how to fetch suggestions from an API while showing a pending state, a pattern most starter kits skip.
- Grouped results: Options can be organized under labeled groups, keeping large datasets scannable.
- Forgiving selection: Auto highlighting the first option means pressing Enter after typing always commits a valid value, reducing form errors.
- Owned source code: Everything is plain TypeScript and Tailwind CSS in your repo, so filtering logic and empty states are yours to change.
Production tips
- Debounce remote queries: When loading items asynchronously, wait 200 to 300 milliseconds after the last keystroke before hitting the API to avoid a request per character.
- Always render an empty state: Show a clear no results message instead of an empty popover, otherwise users assume the component is broken.
- Offer a clear button: As in the clear button variant, a one-click reset is much faster than selecting all and deleting, especially on mobile.
- Cap visible results: Rendering hundreds of rows hurts performance and helps nobody. Limit the list and let typing narrow it further.
Works well with other components
Autocomplete sits on a spectrum with its siblings. Reach for the combobox when selection should come only from the list, the command menu for app-wide actions, and a plain select when options number fewer than ten. For simple text entry without suggestions, use the base input.
In real forms you will usually wrap it in a field with a label and validation message. Search-driven admin screens in our Next.js dashboards use exactly this combination.
Radix UI and Base UI support
Each variant plays nicely with both Radix UI and Base UI form patterns, and Base UI now ships a dedicated Autocomplete primitive that these examples map onto cleanly. Listbox semantics, aria-activedescendant management, and keyboard navigation behave the same in either stack.
That parity means you can standardize your project on one primitive library and still copy any example from this page without rewriting the accessibility layer.
