multiSelectionEnabled property
final
Determines if multiple segments can be selected at one time.
If true, more than one segment can be selected. When selecting a segment, the other selected segments will stay selected. Selecting an already selected segment will unselect it.
If false, only one segment may be selected at a time. When a segment is selected, any previously selected segment will be unselected.
The default is false, so only a single segement may be selected at one time.
