Re: How do you use Custom Widgets (Composites) multiple times?

I have added the new for each instance. I do not understand why I can
not add a composite multiple times. Does anyone know of a way to mimic
this behavior if this is not directly possible. If I need to have 50
identical things on the page, having to create 50 manually is
ridiculous, I should be able to create one that I can use multiple
times.
