When setting a field to "required", on the frontend submission form, the label should represent this state as well.

e.g. by holding a litte span like <span class="req">*</span>. If you don't need it, you could easily hide it via CSS.

Temporarily solved it wthis way:
```
/**
 * Maybe add required span to labels
 */
add_filter( 'rwmb_begin_html', function ( $begin, $field, $meta ) {
 
    if ( is_admin() )
        return $begin;
 
    if ( ! empty ( $field['required'] ) ) {
        $begin = str_replace( '</label>', '<span class="req">*</span></label>', $begin );
    }
 
    return $begin;
}, 10, 3 );
```
Additional question: Tried to apply this hook only to the frontend submission fields, by using filters/prefixes like rwmb_frontend_begin_html, mb_frontend_begin_html, rwmb_mb_frontend_begin_html but none of them worked.

Hi,

This is fixed.

Your filter also works. If you want to make it work only on the front end, you need to check with is_admin() function. There is no filters like rwmb_frontend_*.
