I have 5 values in a Filter column.
I want to restict user to select maximum 3 values out of 5 values.
If user try to select check box of 5th item,either there should be a popup message showing "maximum 3 values can be selected" or
4th values should not be checked.
in below image ,if user try to select any values other than A,B or C,it should not allow user to select.
Great example here: limit number of selections on multiple values quick filter
