Hi,
When using ItemTemplates, the menu wont close when tapping on a root item!
Example:
Do the following on iPad:
Tap the Test1 menu item to open.
Tap the Test1 menu item again to close it -> wont work.
The Test2 menu item works just fine!
The sample works just fine on desktop clients (and even MS Surface tablets), but not on iPad!
Regards
Andreas

Hi,
I was able to replicate the reported behavior. I would like to clarify that this scenario is still not supported on iOS and Android browsers.
However, I have found one possible workaround for a scenario such as your, where there is ItemTemplate only on root items, would be to set ShowToggleHandle="true" and hide the toggle handle with CSS:
Please note that if you add ItemTemplate to a sub-item which has child items, in this case the toggle handle of the corresponding item would not be rendered and visible until you tap that item. Thus, the suggested workaround would fit best a scenario like your where ItemTemplate is applied to a root item.

Hi,
I also tried the ShowToggleHandle="true", but then it will be much harder to expand sub-items since you must hit the small arrow instead of tapping on the entire item (expanding Test1/2 and displaying 22, 23 in the sample).
Found the following workaround instead:
The row that is commented out is replaced...
Don't know if there are side-effects of this, but in our case it seems to work really good!

Telerik.Web.UI.RadMenuItem.prototype._preventDefaultUnderMobile = function (e) { if (!e) { return false; } //var preventDefault = !(this._shouldNavigate() || $(this.get_element()).hasClass("rmTemplate")); var preventDefault = !(this._shouldNavigate()); if (preventDefault) { e.preventDefault(); } else if (!this.get_menu().get_showToggleHandle()) { if (this._shouldOpen()) { if (this.get_isOpen()) { return true; } else { e.preventDefault(); } } } return false; };The row that is commented out is replaced...
