Currently, when an item is expanded in the Menu, the screen readers do not read which item/subitem is expanded. The 'aria-expanded' attribute is not added to the Menu.

The 'aria-expanded' is not added to the Menu and the screen readers do not inform which item is expanded
The screen readers should be able to read which item is expanded in the Menu.
The contextMenu is not acessible. Upon opening, it should capture the keyboard focus and allow navigation by arrow keys, but it does not. (It can be observed here.)
Keyboard use of the contextMenu is also not documented. Keyboard use of the menu is documented here, while the contextMenu is separately documented here.
I'm having resize issues with the Menu control that I cannot sufficiently document at this time (my menu is inside a splitter, it's horizontal and it should be scrollable, but the arrows don't always appear).
I tried working around them by manually forcing a resize. Per documentation:
Each Kendo UI widget has a resize()
method which can be used to trigger a layout readjustment instead of using kendo.resize
. The resize
method of the widget accepts a single Boolean parameter, which defines whether the control should execute its layout adjustment algorithm even if the widget dimensions have not changed ("force"
mode).
However, the Menu widget does not override this method. It only binds to the Window resize event:
$(window).on(RESIZE, kendo.throttle(function(){
that._setOverflowWrapperWidth(initialWidth, initialCssWidth);
that._toggleScrollButtons(that.element, backwardBtn, forwardBtn, isHorizontal);
}, 100));
It's highly probable that the magic value 100 does not fit my use case. However, I cannot force a resize neither by:

### Bug report
Sub Menu item is not opened, if hovered before close animation of another sub-menu-items's child item completes.
Reported in ticket ID 1473199, where a reproduction video is available.
### Reproduction of the problem
1. Run the following [Dojo snippet](https://dojo.telerik.com/@Dimitar-Goshev/EfEmoCon)
1. Hover Item 1, then hover Sub Item 4
1. Hover Sub Item 41 to expand its sub item
1. Quickly move the mouse from SubItem 41 to Sub Item 4 text and then to Sub Item 3 text
### Current behavior
Sub Item 3 is NOT expanded and its child items are NOT visible
### Expected/desired behavior
Sub Item 3 is expanded and its child items are visible
### Environment
* **Kendo UI version:** 2020.2.617
* **Browser:** all
Dojo example.
The sub-menu of "Sub Item 1" does not open.
If the behavior is not exhibited on the first test, click another of the root items and repeat, or reload the example and try again. The issue is more easily reproducible in IE, however it occurs in Chrome and Firefox as well. For more details and a video demonstrating the issue, refer to Ticket ID: 1472421
Sub menus open consistently.
$("#context-menu").kendoContextMenu({
target: "#grid",
filter: "tr.k-state-selected[role='row']",
select: function(e) {
var grid = $("#grid").data("kendoGrid");
var model = grid.dataItem(e.target);
alert( model.age + " " + model.name);
}
});
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.
Reproducible with version 2017.2.504 (R2 2017) and newer.
Dojo example.
Separators are not displayed.
Separators are displayed.
Workaround:
.k-menu-scroll-wrapper .k-menu-group .k-separator {
border-bottom: 1px solid #c5c5c5;
width: 100%;
}
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
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-";
Removing non-existing item from ContextMenu throws a Javascript Error
Uncaught TypeError: Cannot read property 'parentsUntil' of undefined
This is regression introduced in R2 2019
Open this Dojo and run it. Open the browser's console and see the error.
When removing a non-existing item from a ContextMenu no error should be thrown.
Nested Menu items are not being expanded the first time that they are hovered:
The usage of $.uniqueSort() in jQuery 1.10.x throws an error in multiple components like Menu, DropDownList, DropDownTree, and TreeView.
Related to #4665
All components should work properly no matter of the jQuery version used.
To see the expected behavior change
<script src="https://code.jquery.com/jquery-1.11.1.min.js"></script>
to
<script src="https://kendo.cdn.telerik.com/2019.2.514/js/jquery.min.js"></script>
in the provided Dojo.
