When trying to expand the drop downs, some of them do not expand.
It is impossible to give a scenario that always behaves the same, but if
you keep expending the drop downs sooner or later some will stop working.
Hi Robert,
The behavior occurs as the click on the DropDownList propagates up to the Tree Item. This is expected based on the component configuration and you can find more details on the matter here: DropDownList or TextBox in TreeView Doesn't Work.
To handle the scenario, you may wrap the content of the <ItemTemplate> inside a <div @onclick:stopPropagation> </div>.
I hope this will help you move forward with your application. Please let us know if you are facing any other difficulties.
