## onBeforeActive

This event calls user-defined handlers (if there are any) and passes the following parameter:

- itemId - id of the item.

        dhxAccord.attachEvent("onBeforeActive", function(itemId){
            // code here
            return true; // item will be opened
            return false; // item will not be opened
        });
        // or
        function doOnBeforeActive(itemId){
            // code here
            return true; // item will be opened
            return false; // item will not be opened
        });
        dhxAccord.attachEvent("onBeforeActive", doOnBeforeActive);
