I want to know how can I implement grid or list widget that can be expanded and collapsed in mashup like ThingWorx composer like below.
I really appropriate any infomation.
I believe most people would use expression widgets and the repeater widget for this, building the grid manually using the repeater widget
Also you may want to take a look at adding your widget to side bar, header or footer as they can be expanded expanded and collapsed,
