Boundaries and Groups
It’s possible to ‘group together’ topics and branches into related collections. See below for examples:
There are 2 options:
A boundary is a property of a single topic - it groups together that topic and all descendant topics (i.e. the whole branch.) If you add a child topic then it will also be ‘bounded’.
A group is a collection of (possibly unrelated) topics that are ‘bounded’. It’s not possible to add or remove topics from a group. To do that, you must delete the group and recreate it.
A boundary will take the color of the ‘root topic’ and ‘desaturate it’ (as you can see with the orange color above.) There is nothing to configure on a boundary - the color and style is fixed.
A group is more flexible - you can set the color and shape - as can be seen below:
By grouping together 2 floating topics, setting their text to blank, their shape to nothing and the z-order so the group is ‘pushed to the back’ we can create an effect as below:
To create a boundary, select a single topic and click/tap on the boundary toolbar button.
To create a group, select multiple topics and click/tap on the boundary toolbar button (or CMD+G)
To edit a groups’ properties (or delete it) right click or tap somewhere on the edge of the group outline.
