Here's how to do it:
- Select the element or group in FigJam you want to lock in place.
- Click the lock icon above the element, or right-click and choose "Lock", or use Ctrl+Shift+L (Windows) / Cmd+Shift+L (Mac).
- Choose between "Lock all" or "Lock background."
- The element will now be fixed in place, preventing accidental movement or editing.
