Hi @simonator420 for this purpose you have to define GetDropDownMenu and SetDropDownMenu.

GetDropDownMenu is called by Cinema 4D to retrieve the content of the menu to display from the menuInfo dictionary. For more information about this dictionary please have a look at TreeViewDropDownMenuInfo Dict.
SetDropDownMenu is called by Cinema 4D when the user select a value from the dropdown.

Find bellow an implementation example:

    def GetDropDownMenu(self, root, userdata, obj: Entry, lColumn, menuInfo):
        menuInfo["entry"] = 1001 # Select teh second entry
        menuInfo["menu"][1000] = "First Entry"
        menuInfo["menu"][1001] = "Second Entry"
        menuInfo["menu"][1002] = "ThirdEntry"
        menuInfo["state"] = int(menuInfo["state"])  # Workaround to not have warning in Cinema 4D. Will be fixed in the next C4D version.

    def SetDropDownMenu(self, root, userdata, obj, lColumn, entry):
        print(f"User selected the entry with the ID: {entry}")

Finally note that due to an issue that will be fixed in the upcoming version of Cinema 4D, even if you do not change the state, you need to override it to an int value otherwise it will print an error in the console (this is not blocking but still).

Cheers,
Maxime.
