What can Focus Trap Generator do?
Focus Trap Generator is a free online tool that helps developers quickly generate modal focus management code. A focus trap ensures the Tab key cycles within a dialog, preventing it from reaching background content - a requirement of WCAG accessibility standards. This tool supports both vanilla JavaScript and React Hook code styles with configurable options for Esc close, focus restoration, and more.
Core Features
- Dual Code Styles: Vanilla JavaScript and React Hook versions
- Tab Cycling: Tab/Shift+Tab cycles within the container
- Focus Management: Focus first element on open, restore on close
- Esc Close: Optional Esc key to close modal
- Smart Filtering: Auto-skips invisible and disabled elements
- Ready-to-Use Code: Generate complete, directly usable code
Use Cases
Case 1: Modal Dialogs
Add focus traps to modals ensuring keyboard users can only operate within the dialog, preventing Tab from reaching the background.
Case 2: Drawer Panels
When a side drawer opens, focus should be trapped within it and restored to the trigger button on close.
Case 3: Full-screen Overlays
Full-screen overlays (image viewers, onboarding flows) need focus traps to prevent accidental background interaction.
