Hey guys, hopefully very easy question.

Exactly as in the sample I have a list which is filled by items dragged to it. Unlike the sample I can't get my empty list to react to the hover and drop! It reacts when I hover over the web blocks inside the list when I have the droppable area inside the list as well. I have tested all kinds of hierarchies with the web blocks. Is there any CSS-code I need to know or am I down the wrong path on this one?

Many thanks in advance.
