In dev branch when the preview is enabled dragging of components should not be allowed but it does.

temporary workaround for the impatient:

  editor.on('command:run:before:tlb-move', (command) => {
        command.options.abort = editor.Commands.isActive('preview');
      });

Thanks for reporting this, @sumasal.

Great suggestion about in dev branch when the preview is enabled dragging of components should not be allowed but it does.! While this specific feature isn't yet in the core API, there are several ways to achieve similar behavior.

Using the event system:

editor.on('component:update', (component) => {
  // your logic here
});

Alternative approaches:

• Listen to selector:add for CSS selector changes
• Use selector:custom for custom rules
• Tap into the change:* events for fine-grained tracking
• Build a plugin that extends the editor with this capability

Making it official: If this feature would benefit many users, consider opening a formal Feature Request on the GrapesJS repo with:

• A detailed use case
• Code example showing the desired behavior
• Why this matters for your workflow

The core team is receptive to well-motivated feature requests backed by real use cases.
