I have a multiselect. I want users to only be able to select a maximum of 4 items… is there a way to do so? 
Probably the only way would be with an On change workflow which would “guard” for the desired number of items and prevent any other from popping in. Unless there is an option.
Hi! Maybe it’s a bit late for this but I solved this same issue by using the “Disabled condition per item“ setting.
I’m checking if the length of the Values array is greater than o equal to the max number of options I want to set, and that the mapping.value is not contained in the Values array.
This way each option gets disabled when the user reaches the maximum number of selected values, but can unselect an option if they want to change their selection.
Hope this solution is useful for you or anyone looking to solve it!
