Hi @adechriz

Thanks for the question. This is possible by hooking in and modifying the select2 parameters. ACF contains a JS filter which you can use like so:

<script type="text/javascript">
(function($) {
	
	acf.add_filter('select2_args', function( args, $select, settings ){
		
		// limit to 3
		args.maximumSelectionSize = 3;
		
		
		// return
		return args;
		
	});
	
})(jQuery);	
</script>

This code is untested but should work if you place it on the page with your form. You may need to check the $select (jquery object) and test if it is the correct select field.

Thanks
