Set a minimum choice limit in checkboxes

Hi @partaim,

Hope this message finds you well and sorry for our delay.

Our devs shared this new code:

add_action( 'wp_footer', 'wpmudev_limit_validation_checkbox', 9999 );
function wpmudev_limit_validation_checkbox() {
	global $post;
    if ( is_a( $post, 'WP_Post' ) && !has_shortcode( $post->post_content, 'forminator_form' ) ) {
        return;
    }
	?>
	<script type="text/javascript">
	jQuery( document ).ready( function($){
		setTimeout(function() {
			$('.forminator-custom-form').trigger('after.load.forminator');
		},100);

		$(document).on('after.load.forminator', function(event, form_id) {
			$.validator.addMethod("min_selection", function (value, element) {
				let parent = $(element).closest('.wpmudev-checkbox-limit');
                let selected = parent.find(':checkbox:checked').length;
                if ( selected == 8 ) { // Exact selection limit here.
                    return true;
                }
                return false;
			},"Please select 8 options.");
			$( ".wpmudev-checkbox-limit input" ).attr( "min_selection", "min_selection" );
		});
	});
	</script>
	<?php
}

You might also need to add this class wpmudev-checkbox-limit in the styling tab of the checkbox field where you want exactly 8 selections.

Let us know the results.

Best regards,
Laura
