My query does not directly fall under this question. while reading mindmanager for dummies book, i came across a strage (but helpful) mindmap which i have not seen in any of the templates or shared mind maps and after all the effort we could not replicate this mindmap.
could you please throw some light how in the attached picture , the author was able to have the "Level-1 lines (or branches) with text above them (like finances, reunion team in the picture) " instead of "boxed Main topics"
Topic shapes can be created with arrow heads. Look at topic shapes in the Library for inspiration.
Relationships can have arrow heads at either or both ends. You can set the defaults in the map theme.
You can use floating topics with relationships and no topic lines. Okay for visualisation useless for exports.
Check out the Network Builder add in
First, if you're referring to using the topic lines shaped like iMindmap topic branches without boxes which you ask about in your other post, see my response to your question in that thread.
If however you want lines between topics with more conventional arrows, I'd second Andrew's suggestion to look at Network Builder if you want to do this a lot. For occasional use however there is another way, which is to select No Line for the topics under Topic Shape/Format Topic. However this will still leave a little "stub" next to subtopics; to remove this, select white under Line colour to completely eliminate any trace of the lines.
You can then apply relationship lines with arrows at either or both ends as Andrew suggests, and adjust their thickness, style, colour etc.
This is better than using floating topics if you want to export, as Andrew notes. However it only really works down to main topic level as you can't do much to adjust the distance from main topics to subtopics.
