i just wanted to know, if you can use one widget as a "master" widget? Meaning that you can implement this widget on multiple pages with content. And when the content changes, you can adjust the "master" widget, and all instances of it will follow? Can you do this with AEM out of the box, or with little programming effort? Or do you need to programm alot for this?
Can't you use sling:resourceType and sling:resourceSuperType properties for the same?
Like define the sling:resourceType for the parent component and then use sling:resourceSuperType in the instance of it so that the changes are immediately reflected.
