Hi. I was trying to create a drop down list, where the user could select multiple options from the list, but still the options selected must be unique within a Cell. For Instance: if a Dropdown has A, B, C as values, selecting A and C is a valid selection, but selecting A, C and A is not.
I did manage to create a multi-select drop down, (which is a comma separated strings) but could not implement the unique string constraint. Any ideas
