Also, maybe this isn't a common issue and would be solved by better designed models but.. using an ng-repeat against a list with some heterogeneous data.. ng-if works well to show only the UI components that apply to the object in question without rendering things for no reason and then hiding them. For example if you have a list of objects where some particular action might apply only to a portion of them.
