[Question] Propagate different value

Any way I can add selectable: true to the parent and propagate a false value?

I'd say that the only way is to create a wrapper in the middle:

<parent> <-- selectable
	<div data-gjs-selectable="false" propagate..> <-- not selectable
		<child>
		...

And, in a similar vein, is it possible to override propagation down the line?

No, you can't stop the propagation only via props

If you need, you all the stuff, about the propagation, happens here: https://github.com/artf/grapesjs/blob/dev/src/dom_components/model/Component.js#L125-L135

I'm also facing this issue, where I have created a custom components with image wrapped inside a <a> tag, when I click on the component, image tag click is triggered rather than <a> tag click. Is there any solution to this?
