GrapesJS version

What browser are you using?

Vivaldi

Reproducible demo link

https://grapesjs.com/demo.html

Describe the bug

How to reproduce the bug?

  1. Press Ctrl+Z after doing an action, to undo it
  2. The action is reversed, but my browser also reopens the last closed tab

What is the expected behavior?

Stopping the browser from performing the default keybinding.

What is the current behavior?

Ctrl+Z event propagation is not stopped in JS, so the browser still performs the assigned keyboard shortcut.

Thanks for reporting this, @bohwaz.

Great question about Undo (Ctrl+Z) is not cancelling browser keyboard shortcut. The recommended approach with UndoManager is to use the event-driven API.

Start here:

  1. Check the GrapesJS documentation for your specific module
  2. Look for the on() event listener method
  3. Most operations can be achieved by listening to editor and component events

Common patterns:

// Listen for changes
editor.on('change', () => console.log('something changed'));

// Component lifecycle
editor.on('component:mount', (c) => console.log('component ready', c));
editor.on('component:update', (c) => console.log('component updated', c));

If you're still stuck:

  • Share a minimal CodeSandbox reproduction
  • Include what you've already tried
  • Mention your GrapesJS version
