Currently, if a NavBar's FullExpand property is set to "false", it is possible to collapse an expanded top-level item by clicking on it a second time.

I would like the option to disable this. That is, with the option set: when an item is expanded, you cannot collapse it by clicking on it; it only collapses when another item is expanded. This behavior would be the same as when FullExpand is set to "true" (except the menu items wouldn't automatically expand to the full height of the control).

As an added bonus, the HoverCssClass for the expanded item should be disabled (since the item is no longer clickable). But this could be handled by a separate HoverExpandedCssClass as discussed in one of my previous posts.

We are ever expanding the available options and properties for our components and appreciate your feedback, we will definitely add this to our list of desired features.

Has this feature been added yet?
I also would like the option the disable the expand/collapse feature and have everything expanded all the time.

With some javascript and the built in client side API we can achieve this.  Based on 2009.1 or later.

 

Add a client event for BeforeCollapse in the NavBar

 

<ClientEvents>
  <ItemBeforeCollapse EventHandler="BeforeCollapse" />
</ClientEvents>

Now in this method, set_cancel(true) to the event arguments.

 

<script>
  function BeforeCollapse(sender, e) 
  {
    e.set_cancel(true);
  }
</script>

Hope this helps.

 

Cheers,
