Receive an event when Dropdown is closed?

Hi there,

We are having a very particular issue that we are quite sure has a very easy solution, but we can't find the proper way to handle this. Here's our case scenario:

When we navigate our menus using keyboard (or a controller), when the user interacts with a dropdown option, our menu navigation is disabled so Up/Down only works as a selector inside the dropdown list options. Everything good so far, then when an option from the dropdown is selected, the onValueChanged event is thrown and the dropdown list is closed, so we use that event to give back the control to the UI. The problem comes when the user selects the same option that was already selected in the dropdown, since the onValueChanged event is never called and then the user is stuck because the dropdown list closed but the controls were not given back to our UI system due to the lack of event.

To solve that, we just need either to know when the dropdown list closes so we can use it instead of the onValueChanged event, or some sort of event/flag/whatever that is always called when an option of the dropdown is selected, no matter if it's the same or not.

Is there any simple way we can achieve this? We are using Unity v2017.4.11f1 from the LTS support builds, by the way.


Thank you very much in advance.
