Enable loading of submaps on demand
The default system behavior loads submaps when you open the parent map in DITA Map view. If you enable loading on demand, the parent map opens normally, but submaps load only when you expand them or when an action (such as Select In Map) needs to expand them.
About this task
Submaps can slow load times because each submap loads independently along with its topics. For example, a map with 100 topics loads quicker than a map with 10 submaps of 10 topics each. Having submaps load on demand can speed up how quickly the parent map loads.
To enable this feature:
Procedure
- From the Window menu, select Preferences.
- Select .
- Select Load sub-maps on demand.
- Click Apply.
- Click OK.
