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: http://www.advancedcustomfields.com/resources/acf-validate_value/
