<div type='discussions-op-text'>

<sup>Originally posted by ltenti August 17, 2021</sup> Hi everyone,

I'm wondering how to address this kind of scenario:

  • I have to allow the users of my application to edit a webpage
  • the webpage has some fixed part that the user can't edit
  • the whole HTML is produced server-side by a legacy subsystem, but some part inside it has to be freely editable by the user I realized a custom component that fetches the legacy HTML from the server and "inject" it in the canvas with a model.components(data) statement. I was thinking about creating a new component type (something like doNotEditMe) with property "editable" set to false and then assigning data-gjs-type="doNotEditMe" to all the elements of the original HTML that has to be not-editable. Do you think I'm crazy?

Thanks for reporting this, @ltenti.

Great suggestion about Partial parse! 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.
