We have a we issue we use rad menu in my work and we adapting the sites to responsive but when we click on the menu to navigation to a drop down item it does not allow us to click to the sub menu items only the main navigation url is opened. Is this a bug when viewed on tablets ???
One suggestion is you can set the ShowToggleHandle property of the RadMenu that helps to improve the RadMenu's usability and to provide unified behavior when
used on a traditional desktop mouse centric environment and in touch
enabled one. Clicking or touching the ToggleHandle will show or
hide the sub items of the corresponding item, without executing its
action which could be either navigation or server-side event execution. Please note that this feature is introduced in the latest Q3 2013 release.
