In the kendo ui menu, we need the ability to associated a number (or primary key) with the menu so that when it is clicked we can then use this id and make an async js callback or the like.  At the moment the only thing we have available is the menu item text.  What happens if the menu has two menu items with the same text? ie File -> Properties and Folder -> Properties?

Please, I don't know where to direct this comment to that is why I am contacting sales for possible onward forwarding to the appropriate tea

I prepared a dojo example. https://dojo.telerik.com/oKIkuCaP

As can be seen from example, the MVVM context menu seems to ignore data-copy-anchor-styles option.

Current solution for us is to extend the kendo.ui.ContextMenu and set the copyAnchorStyles option to false.

I'd like to request the ability to add a public method with the functionality to focus on a specific menu item for navigation purposes.  

Bug report

Defining a custom namespace with Kendo.ns stops the displaying of all submenus in the Menu component.

This is a regression represented in R2 2019

Reproduction of the problem

1. Open this Dojo and run it.
2. The Menu component is being rendered
3. Move the mouse cursor over the Menu.
4. A thin grey line appears under each section of the Menu. No submenus are being displayed

Expected/desired behavior

The Menu component should work properly even when a custom Kendo namespace is being defined. To see the expected behavior put a comment on the following line:
kendo.ns = "kendo-";

I'm showing a js error and am not able to see the demo work.  Thanks!

Add an overflow option/setting to the menu control. If the height or width of a menu group exceeds the current page viewport height or width, a new section would be added to the beginning and end of the menu to allow scrolling without adding scrollbars. 

Example - If a horizontal menu has a sub menu that exceeds the height of the current page viewport, add sections to the top and bottom of the sub menu to allow the menu items to be scrolled up or down (mouseover or click) without adding a scrollbar to the sub menu.
