Forms

Tags Input

Type and commit free-form tags as removable chips.

Import

tsx

import { TagsInput } from "@cronus-ui/ui";

bash

npx cronus-ui add tags-input

Examples

Default

Type free-form tags and commit each with Enter or comma; they render as removable chips. Backspace on an empty field deletes the last tag, and `max` caps the total.

Topics

designreact

Press Enter or comma to add. Backspace removes the last tag.

tsx

function TagsInputDemo() {
  const [tags, setTags] = useState<string[]>(["design", "react"]);
  const labelId = useId();

  return (
    <div className="flex w-full max-w-sm flex-col gap-2">
      <FieldLabel id={labelId}>Topics</FieldLabel>
      <TagsInput
        value={tags}
        onValueChange={setTags}
        aria-labelledby={labelId}
        max={6}
        placeholder="Add a topic…"
      />
      <FieldDescription>
        Press Enter or comma to add. Backspace removes the last tag.
      </FieldDescription>
    </div>
  );
}
