Expand Input

Buttons 4

About

An animated pill-shaped subscribe button that expands into an email input, shows a loading spinner on submit, then a drawn checkmark on success.

Built with React and Tailwind. Copy the prompt and paste it into Claude Code, Cursor or Lovable: your agent adds Expand Input to your project and fits it to your theme.

Code

How Expand Input is used: the demo's code. The component's own source comes with a free account.

Usage.tsx

import { ExpandInput } from "@/components/ui/expand-input";

export default function ExpandInputDemo() {
  return (
    <div className="flex min-h-[400px] w-full items-center justify-center bg-background p-10">
      <ExpandInput
        label="Subscribe"
        placeholder="you@example.com"
        successLabel="You're in!"
        onSubmit={(email) => new Promise((resolve) => setTimeout(resolve, 800))}
      />
    </div>
  );
}
