What is the best way to implement a project selection screen like Unity, Visual Studio etc, with multi line selectable?

[kevyuu]

I want to implement a multi line project selection screen, if possible without using the draw api.


Something like this. I have try to use the selectable widget, but it will only work for a single line text.
I manage to get the layout using group and IsItemClicked(), but how do I change the color of the group background when hovered?
