I'm using scheduler pro with tree enabled and I have some resources with children items.
So, I assigned some events to the first resource level and I assigned to some childrens too.
Then when I click to edit an event, only the first resource level is displayed in "resources field", the children resources are not displayed.
When I click to see a list of resources I can see an arrow after the resource name, but when I click there, nothing happens.
I am using multiple assignment mode and then I assign the same event to both the "parent" and the "child".
What I noticed was that if I leave the parameter "expanded: true" everything works fine, but if I start with "expanded: false" then it doesn't work correctly, because I can't see and select the "child" in the edit modal, I can only select the parent.
