We will assume the menus have the Id's of menu1 and menu2.

 

Please feel free to share a better way if you have one! I'm no expert in jquery.

 

 

$("#menu1").change(function() {
  val = $(this).val();     
    if(val == 0 ){
      $("#menu2").val(0);         
    }        
});

Or if you just want it copy another:

 

$('#menu1, #menu2').change(function(e) {
    var $this = $(this),
        other = $($this.attr('id') === 'menu2' ? '#menu1' : '#menu2');
    
    other.val($this.val());
});
