How to edit a button if the button has an action (opening a modal window)?

You have to create a custom component for that button if it requires custom logic/behavior from what the original HTML does

Thanks for reporting this, @sashapawlow726.

Great suggestion about FEAT: how to edit a button if the button has an action (opening a modal window)?! 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.
