Adding dynamic content underneath a tree widget item
I'm trying to implement something along the following lines http://i.imgur.com/bu7ETih.png
I would like to have a list of items like in the image (Input settings, mosaic size, mosaic rendering etc.) and once I click each I want a sub-window or sub-box to appear...with dynamic content, like radio buttons, sliders, etc. Any leads on how to go about implementing this the most intuitive way?
