We have a treeview structure of 8 first-level folders. We have found that when a first-level folder has more than 50 second-level folders within it, the second-level folder can not be expanded to see third-level folders. The expand arrow just disappears once it's clicked. If we lower the amount of second-level folders in an individual first-level folder to 50, the expand works again.
For example
Parent Folder 1
->Subfolder 1
->->Sub-subfolder1
->Subfolder2
...
->Subfolder51
In this example, Subfolder 1 will not expand to display sub-subfolder1.
Is there a limit to how many folders can be within another folder?
