Adding elements to Mindmap/ Horizontal tree

Question

This may be a basic question, but I could not figure it out even after spending a while on it and the documentation.

How do I add new elements/nodes to a mindmap/horizontal tree?

The blue arrow lets you duplicate the same element (like I've done for Topic) but I can't seem to figure how to add for instance a branch from the Topic like in the figure below:

Is there any documentation that I may have overlooked on this?

Thanks!

Answer 1

I went through the page again after David mentioned it. I figured how to do it after that but it is not clearly captured on that page though.

The solution is to hold Ctrl and drag and drop the required shape on the node where it is to be inserted.
