I spent all night looking this up and can\'t find it.
Is it possible to have an Excel/Office add-in that has both content and taskpane components?
Really, I
At this time you can only show a taskpane or a dialog through an add-in command. It is a scenario that we've heard and we have in our roadmap to address (not committed date yet). We can reply to this thread when the functionality is available for preview.
Is there a particular scenario you want where you'd need this to be a content add-in (i.e. a data visualization?).
thanks
