How to clear a Combobox set as DropDownList in Application Studio?

[mng (Matt Ng)]

I have a combobox in application that is set to DropDownList as I only want to be able to select from the list. However blank is a valid value and I would like the ability to clear the combox. Delete and backspace don’t seem to do anything, Is there any way to do this or do I have to switch to a DropDown instead of a DropdownList and allow users to be able to freeform type whatever they want? Thanks.

In ur combo box properties the before last option in the advanced settings is “Allow Custom” and check that box you will be able to delete the value that is entered in the combox.

Not sure why its built like that.

Hope that helps!
