Is there any way to know how many options have been selected from a Multiselect control?


I want to apply a condition that a user has to select at least 3 options from a multiselect control to proceed further. So is there any way to apply such condition in Validations?



If you check the Validations section. All the Multiselect controls will have an operator called “Minimum Select” and “Maximum Select”.
You can use this option to give the minimum select number of 3 for ensuring that the user selects atleast 3 options.

Hope this helps.
