Styling ListView.GroupStyle with WrapPanel

Ok, here is my pretty simple problem.

I have ListViewone that I created to look like Windows Explorer.

Now I want to group the elements inside. Therefore, I defined a GroupStylec Expanderto group it. Now the grouping is beautiful.

What I do not like is that now my ListViewdisplays each group on a separate line, while I would like to have some extension packaging to display many groups on one line.

An image is better than any text, I think.

I can’t find which property I need to erase in order to make it GroupItemssuitable in WrapPanel, as well as for elements.
