Using widgets developed by other people, I've seen that in some ways it is possible to split a widget into multiple components. For example I've seen a gallery widget, where as soon as you drag the widget into muse, you get a component in which you can add/handle all your images and an other component where you customize the style/behaviour of the gallery. That means that you drag one widget into Muse but get two or more individual blocks with their own individual settings.
How is this done? I couldn't find any hints in the Mucow-Doc...
