Hello,
I have the following code:

    $ksm = new KoolSlideMenu("ksm");
    $ksm->scriptFolder =  "KoolControls/KoolSlideMenu";
    //Customers menu
    $ksm->addParent("root", "customers", "Customers", null, true);
    $ksm->addChild("customers","cust_manage","Manage", $url . "/MySys/customers_management.php");
    $ksm->addChild("customers","cust_report","Reports", $url . "/MySys/customers_reports.php");

Is it possible to open the KoolSlideMenu child options urls in new tabs?
I'm currently using the version 8.2 of KoolPHP.

Ok, just figured the Client side API in the next day I submited the last post. I solved the situation using the following code:

$ksm = new KoolSlideMenu("ksm");
$ksm->scriptFolder =  "KoolControls/KoolSlideMenu";
//Customers menu
$ksm->addParent("root", "customers", "Customers", null, true);
$ksm->addChild("customers","cust_manage","Manage");
$ksm->addChild("customers","cust_report","Reports");
...

<form id="form1" method="post">
    <div class="box">
        <?php echo $ksm->Render();?>
    </div>
    <div class="clear"></div>
    <script type="text/javascript">
        ksm.registerEvent("OnSelect",function(sender, arg) {
        switch (arg.ItemId) {
            case "cust_manage":
                window.open('customer_manage.php', '_blank');
                break;
            case "cust_report":
                window.open('customer_report.php', '_blank');
                break;
            ...
        }
    </script>
</form>
