Hi is it not possible to let a popup come ip when I “mouse over” over a ComboBox? I need an interactive combobox. The only way I found was with a link to a next mockup with the combobox open. But that means an extra mockup for every state… a lot! 
Thank you very much!

Hey @fosi,
We like to think of Mockups as a competitor to pen and paper, so we limit our interactivity to mimic that what you would see with pen and paper. Unfortunately, that means that there are no mouse-over actions with our wireframes. I’m sorry about that.
You can link a closed combo box to an open one, and simulate that interactivity. Or, you could use markup to illustrate what would happen when a user mouses over the combo box.
Hopefully that helps!
