It would be great if it was possible to use templates with an expansionpanel. In my case would like to add an icon preceeding the title of the expansionpanel. Template support would be great as it adds more flexibility.
Еxpanding/collapsing nested panels collapse the parent panel as well
Reproduction of the problem
Can be replicated in the following Dojo:
Collapsing or expanding a nested panel collapses/expands the parent panel
Collapsing/expanding the child panel shall not collapse/expand the parent
