What is the Single Expand option, and when should I use it?
The Single Expand option reduces clutter and lets you focus on a particular section of the map. When it is turned on and you expand from a topic at a given level of the map, the branches shown from other topics at that level collapse.
Turn Single Expand on (or off)
This option is a toggle. There are three ways to turn it on (or off).
Method 1: Click the Single Expand button
Method 2: Select from the Map Settings dropdown list
Watch the effect
The following steps illustrate the effect of Single Expand being on.
Draw a map
At the outset, as you are drawing a map, all topics remain visible, regardless of the Single Expand state. It is later, when you have opted to collapse topics, that the Single Expand state becomes relevant.
