Bug report

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.

https://www.w3.org/TR/wai-aria-practices/examples/menubar/menubar-1/menubar-1.html

Reproduction of the problem

1. Open the demos
2. Focus on the Menu and expand an item.

Current behavior

The 'aria-expanded' is not added to the Menu and the screen readers do not inform which item is expanded

Expected/desired behavior

The screen readers should be able to read which item is expanded in the Menu.

Environment

• Kendo UI version: 2021.1.119
• Browser: [all ]

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:

1. calling resize() on the widget
2. calling resize(true) on the widget
3. calling kendo.resize() on the container.

### 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

### Environment
* **Kendo UI version:** 2020.2.617

Bug report

Reproduction of the problem

Dojo example.

1. Click "Test1" and immediately hover "Sub Item 1"

Current behavior

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

Expected/desired behavior

Sub menus open consistently.

Environment

• Kendo UI version: 2020.2.617
• jQuery version: x.y
• Browser: [all]

Hi

I was wandering around on the internet for the responsiveness of the Kendo UI menu but didn't get success, even I read your forum, someone has posted about this, but you have written that we have not created responsive menu yet.

Please see the attached screenshot 

https://www.telerik.com/forums/menu-and-bootstrap

Please create your menu responsive as we need to use in our application.

Bug report

Reproducible with version 2017.2.504 (R2 2017) and newer.

Reproduction of the problem

Dojo example.

1. Open a submenu in the top Menu (it has scrollable: true set).

Current behavior

Separators are not displayed.

Expected/desired behavior

Separators are displayed.

Workaround:

.k-menu-scroll-wrapper .k-menu-group .k-separator {
  border-bottom: 1px solid #c5c5c5;
  width: 100%;
}

Environment

• Kendo UI version: 2019.3.917
• jQuery version: x.y
• Browser: [all ]

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-";

Environment

• Kendo UI version: 2019.2.619
• jQuery version: x.y
• Browser: [all]

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.

Nested Menu items are not being expanded the first time that they are hovered:

https://dojo.telerik.com/EcEsoNAK

Bug report

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

Reproduction of the problem

Open this Dojo and run it. Open the browser's console and see the error.

Expected/desired behavior

When removing a non-existing item from a ContextMenu no error should be thrown.

Environment

• Kendo UI version: 2019.2.514
• jQuery version: x.y
• Browser: [all]

Bug report

The usage of $.uniqueSort() in jQuery 1.10.x throws an error in multiple components like Menu, DropDownList, DropDownTree, and TreeView.

Related to #4665

Reproduction of the problem

1. Open this Dojo and try to use some of the components in it.
2. Error messages appear in the console and the components get stuck

Current behavior

Expected/desired behavior

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.

Environment

• Kendo UI version: 2019.2.514
• jQuery version: 1.10.x
• Browser: [all]

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

Please fix your demo page.

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

Hi Telerik Team,

Just wanted to point out that it would be nice if you could kindly put "-Bruce Lee" after the "Content is like water" quote. 

Thank you

My suggestion in for Marketing new products and services.

May Telerik could create a Telerik Store, for his customers sell directy to each other, sub systems, or even full systems or custom components and Themes.

Progress Telerik wins a part of the trade.

This is my idea for future community, 'cause robots will grow very fast and a Store for your plataform would be good way for humans improve each other. Could the Store developers sell too his task force for jobs targeting Telerik products.

Hi,

ContextMenu scroll ( contextmenu height ). ( telerik RadContextMenu do it )

Thanks

Almost everything in the Kendo UI library can have its visual aspect changed by use of templates.

Unfortunately this does not apply to the visual interface for the Kendo Menu object.

Please can you consider adding this functionality.
