Control which level is expanded/collapsed after load.


I have hierarchy like this:


Is it possible to load the gantt for the first time with expanded levels root, level1, but not expanded level2 ?

Meaning there are a lot of tasks on level2 but they are not important to show after load, if the user wants to expand particular level2 he/she will do it manually by clicking expand. Other upper levels are important and they should be expanded after load.

In another words, how to load all tasks but to expand only first two levels ?


Please, check this demo:
