  • Hi @kolhoffmmm

    Have you tried using acf/validate_value filter to perform a custom validation of the number of terms selected by the user?

    It is pretty simple, the code should look something like this:

    function my_validate_value($valid, $value, $field, $input) {
    	if(!$valid) {
    		return $valid;
    	if(sizeof($value) > 3) {
    		$valid = 'You can only select 3 terms';
    	} else {
    		$valid = true;
    	return $valid;

    For more info, check out the docs for acf/validate_value. Here is the link:
