The next method gets the next selectable item. The first item is selected if no item is active or the last one is active. It returns null if none is selectable.

$(function () {
    var returnsValue; // Type:  any
    // Parameters
    var event; // Type:  event
    
    returnsValue = $(".selector").wijmenu("next", event);
});

function next( 
   event : event
) : any;
