I'm looking at the Dropdown Tree control as it's almost exactly what I'm looking for to solve my problem. There is one thing however that I cannot seem to do with any of the built-in settings.
Let's assume a data structure as such:
Item 1
Item
1.1
Item
1.2
Item
1.2.1
Item
1.2.2
Item 2
Item 2.1
For my use case the user should only be able to select Item 1.1, Item 1.2.1, Item 1.2.2 and Item 2.1. If you look closely you will see those items don't have any children. That's the criteria. Only items with no children should be selectable. This is because I render items with "paths" into a Tree for easier navigation as many options are available. Only those unique items are able for selection:
Item 1//Item 1.1
Item 1//Item 1.2//Item 1.2.1
Item 1//Item 1.2//Item 1.2.2
Item 2//Item 2.1
Is there any way to do this ?
