Hello Pål,

I am afraid that sharing a single Toolbar among multiple widgets is not supported by the Editor. Having that said, I have converted the following thread to a feature request. It could be found in our Feedback portal, where you could cast your vote for it.

As a possible alternative, I would suggest you to review the Inline mode of the Editor. That would render the respective Toolbar only when the editor in question is focused.

Regards,
