Bug report
Vertical ContextMenu missing wrapper element <div class="k-menu-scroll-wrapper vertical">

Reproduction of the problem
Dojo: https://dojo.telerik.com/ObifIvOS/2

Result:

Environment
Kendo UI version: [2022.2.510 or newer]
jQuery version: [all]
Browser: all

Steps to reproduce:

1. https://dojo.telerik.com/ovUhajAp
2. Run the dojo and click the "Append" button

Expected: New child list item under the "Fifth Item" menu is bold and purple
Actual: New child list item is not formatted

If you inspect the DOM for the appended item, you will notice that the list item was not appended to a ul. A child ul was created but it is empty and has an undefined id.

It looks like this bug was introduced in 2023.2.606

Bug report

When utilizing the content property for a Kendo UI Menu's DataSource, the MenuItem's content is not created as expected based on documentation.

Reproduction of the problem

Here is a Progress Kendo UI Dojo which replicates the appearance issue.

Expected/desired behavior

This is a Dojo with an older version that is working as expected.

Workaround

Define the content in a nested Items property:

           {
             text: "<b>Item 2</b>",
             encoded: false,                              // Allows use of HTML for item text
             items: [{
               content: "text",                            // content within an item
               contentAttr: {
                 style: 'border: 1px solid red; padding: 2px;', // Add attributes to the content container
                 custom: 'value'
               }
             }],                             
           },

Here is a Dojo of the workaround in action.

3. Hover the subitem once again

Current behavior

Environment

• Kendo UI version: 2021.3.914
• Browser: [IE]

When new item with sub-items is appended or inserted (before/after) into kendoMenu or kendoContextMenu then "aria-expanded='false'" text surprisingly appears right to the new item. This defect can be reproduced just by running the demos published for kendoContextMenu or kendoMenu's methods such as append, insertAfter or insertBefore, or as shown bellow. The defect is reproduced on Windows and Linux, as well as on Firefox, Chrome and Edge.

Bug report

When openOnClick is enabled for the root Menu items and also the scrollable option is enabled, when moving the cursor over different subitems, previously hovered remains opened.

Reproduction of the problem

1. Open the Dojo
2. Click on Item 2
3. Hover over Sub Item 1
4. Hover over Sub Item 1.2
5. Move the cursor to hover over Sub Item 2

Current behavior

Both submenus remain opened - the one for SubItem 1 and for SubItem 2

Expected/desired behavior

The previously opened submenu (Subitem 1) should get closed.

Environment

• Kendo UI version: 2021.2.511
• Browser: [all ]

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.

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.
