Fraction Checkbox

Forms

About

A select-all checkbox for a list that shows partial selection as a gauge, filling its box in proportion to how many child items are checked instead of just showing an indeterminate dash.

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

Code

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