Is it possible to collapse a node when one of the nodes below are clicked?  I have a navigation control with multiple nodes with some nodes having "sub" nodes.  When one of the sub nodes are clicked the page does what I want (navigate a separate panel to a new page) but the node stays expanded unless another parent node is clicked on the navigation control itself is clicked.
Thanks,
Jeff

Some more information.  I had a RadSplitter with two RadPanes, when I had the RadNavigation in Pane1 and clicked on an item, I would open a separate page in Pane2, clicking in Pane2 did not collapse the RadNavigation, I had to click anywhere in Pane1 to collapse the RadNavigation.  I stopped using the splitter and it seems OK now.  It would be nice to have the option to have the Nodes auto-collapse after being clicked.
Thanks,
Jeff

Hello,

To make the RadNavigation nodes collapse on click you can subscribe to the control's OnClientNodeClicked event and call the _collapseAll method in its event handler as shown below:
function OnClientNodeClicked(sender, eventArgs) {              
    if (eventArgs.get_node().get_level() > 0) {
         sender._collapseAll();
    }
}

<telerik:RadNavigation ID="RadNavigation1" runat="server" OnClientNodeClicked="OnClientNodeClicked">

Hi Ivan,

This technique doesn't appear to work on  the hamburger menu when there is a second level.  It closes the second level but NOT the main hamburger menu.  How do you force that to hide?

Regards

Jon

Ah, I've realised that the hamburger isn't a normal node and that would explain it not collapsing.  I've now found the _collapseSandwich function and used that, works very well now.  

Is this going to be added as a proper function so that it doesn't get dropped after any internal rewrites?  I always get worried about using the underscore functions.

Regards

Jon

Hi Jon,

Thank you for your concern with RadControls - we will do our best to add public methods for expand and collapse of the MenuButton or the "sandwich" as soon as possible.
