It would be great to be able to simply connect the menu widget to a DataSource to populate. It will allow for a data driven menu, instead of having to handle that logic on the client side.

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.

Kendo UI is so customizable, which is why I'm transitioning away from DHTMLX, jQuery UI and jQuery Mobile. The Menu currently allows some control over click events, but I think, in keeping with Kendo's current customization options, full control over click and hover events would be a great thing to have.

I was able to mock this by commenting out 1 line of code, so to add as a configure option, this should be pretty easy to implement.

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?

According to the documentation at:

http://docs.kendoui.com/kendo-ui/api/web/menu#configuration-dataSource 

you can add the following information to a dataSource:

text
cssClass
url
encoded
content
imageUrl
spriteCssClass

However you cannot add an id to the menu item you are creating.  This makes it very difficult to remove items by using:

menu.remove("#Item1");

The only way round this is to assign a unique class to each menu item and then remove them using:

menu.remove(".news");

If an id can be added that would be great.  You have an example here:

http://docs.kendoui.com/kendo-ui/api/web/menu#methods-remove

Which is what we would like to do except the items will be created via a program and not static HTML.

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.

Hi,

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

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

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]

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 ]

Bug report

When items are added to the Menu component using the append() method, the select event of the items is not triggered.

Regression introduced with 2023.2.606

Reproduction of the problem

1. Open the following Dojo example - https://dojo.telerik.com/@Zornitsa/UJASiWUq
2. Select the "Sub Item 1" menu item.

Current behavior

The alert about the item selection is not appearing, i.e. the select event is not triggered.

Expected/desired behavior

The select event should be triggered and the alert should appear as expected.

Environment

• Kendo UI version: 2023.3.1010
• Browser: [all]

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.

Environment

• Kendo UI version: 2023.3.1114
• jQuery version: All supported versions
• 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

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]

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]

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

https://dojo.telerik.com/EcEsoNAK

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.

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]
