Currently, the Virtualized DropDownList does not handle the autoWidth property, as describe in the offical client-side API documentation.

It would be beneficial if there is a way to circumvent around this limitation.

Please add support for Prefix / Suffix Adornments for DropDownList

Hi Team, 

I would like to request to add a class which associates with the Kendo DropDownList.  This way, the developer could use CSS instead of jQuery to change the style of the specific popup.  

Thank you!

Bug report

The value of a disabled DropDownList is not announced in the below screen reader -> browser combinations:

NVDA with Chrome
JAWS with Chrome

The value is correctly announced by NVDA in Firefox.

After testing the scenario with the ComboBox, the value was correctly announced in all screen reader -> browser combinations.

Reproduction of the problem

1. Open this Dojo example in Chrome with JAWS/NVDA - https://runner.telerik.io/fullscreen/ERAxiqIy/3
2. Click the Enable checkbox
3. Select a value from the DropDownList
4. Click the Enable checkbox again.
5. Focus the Checkbox and press the down arrow key.

Current behavior

The screen reader announces the disabled state of the DropDownList, but does not announce its value.

Note - the value of the regular select element below the DropDownList is announced.

Expected/desired behavior

The value of the disabled DropDownList should be announced in the above mentioned combinations.

Environment

• Kendo UI version: 2023.1.117

Bug report

Binding an MVVM DropDownList to a property that is null results in an error on the console.

Reproduction of the problem

1. Open this example - https://dojo.telerik.com/@martin.tabakov@progress.com/eNUMeLix

Current behavior

An error is thrown

Expected/desired behavior

No errors should be thrown

Bug report

The change event is not fired when using the keyboard navigation in the DropDownList, if we first click in the filtering input.

Reproduction of the problem

1. Open the Dojo - https://dojo.telerik.com/@NeliKondova/AnACEzIV
2. Open the popup and use the up and down arrows to navigate between the items.
3. Click in the filtering input.
4. Press enter to select an item

Current behavior

Item is selected, but the 'change' event is not triggered. If we do not focus on the filtering input, the change event will be fired. It will be fired also if the mouse is used. - screencast

Expected/desired behavior

The change event should always be fired when the selection in the DropDownList is changed, even if the user clicks in the filtering input.

Environment

• Kendo UI version: 2022.3.1109
• Browser: [all ]

Bug report

When navigating between inputs and after using Shift+Tab for focusing on a previous input the DropdOwnList popup does not close on pressing 'Enter' key.

Reproduction of the problem

1. Open Dojo
2. Focus the text input
3. Press Tab to focus the DropDownList
4. Press shift-tab to focus the text input
5. Press again Tab to focus the DropDownList
6. Press Alt+down to expand the dropdown
7. Press the down arrow to select an option in the dropdown
8. Press Enter key

Current behavior

The popup does not close. If we directly focus the DropDownList and follow steps 6-8 the popup will close.

Expected/desired behavior

The DropDownList should close when pressing the 'Enter' key.

Environment

• Kendo UI version: 2022.3.1109
• Browser: [all]

Steps to reproduce:

1. Open the dojo using Google Chrome browser;

2. Open the first dropdown list;

3. Select any option from the list;

4. When the drop down closes, press Ctrl+V. The selected value changes for each time the keys combination is used.

 
Expected: CTRL+V combination does not trigger value selection.

Describe the bug
While the loading icon is visible in the DropDownList when fetching data, the widget's height is changed.

To reproduce

1. Open this Dojo example - https://dojo.telerik.com/AFuQItIv/4
2. Select an item in the first DropDownList

You can compare the height of the two dropdownlists

Expected behavior
The height of the DropDownList shouldn't change when the loading icon is visible.

• Kendo UI for jQuery

Affected browsers (please remove the unneeded items)

• All

The dropDownList supports several keyboard shortcuts as documented in https://demos.telerik.com/kendo-ui/dropdownlist/keyboard-navigation. However, when e.g. a KeyDown event is triggered (and handled) by the widget, its propagation is not stopped. This behavior can be witnessed in this DOJO.

In our case, we e.g. use dropDownLists inside dialog windows that can be closed via ESC. When pressing ESC while a dropDownList is focused, this not only closes the dropDownList (as expected), but also closes the dialog.

The dropDownList should stop the propagation of events that it handled.

Hi Team,

I'd like to request the functionality to add a Clear Button  for the Kendo UI DropDownList similar to the ComboBox.  

Thank you!

Bug report

When the DropDownList is used as an editor in the Gantt, sometimes the DropDownList popup closes on double-click. The issue is observed when the trackpad's click is set to light and a double-click is performed.

Reproduction of the problem

1. On a Macbook Pro set the trackpad click to light
2. Run this dojo
3. Double-click on an item in the title column

Current behavior

Sometimes the DropDownList opens and closes.
Screencast

Expected/desired behavior

DropDownList should remain open

Environment

• Kendo UI version: 2021.1.330
• Browser: [all]

Bug report

Even if no filtering is configured, when the delay option is different than 0 navigation between the items in the DropDownList does not work correctly.

Reproduction of the problem

1. Open the Demo
2. Focus/Open the DropDownList
3. Click 's' - Small is selected
4. Click 'l' - Large is selected
5. Repeat multiple times

Current behavior

The correct item is not always selected. In the demo, no delay is configured, but the default value is 500. The delay is supposed to affect the DropDownList only when filtering is enabled.

Note: Currently, when the filter option is configured, changing selection without opening the DropDownList is not possible.
https://dojo.telerik.com/@iankodj/AhUgaXuf

Workaround

Set delay to 0 - Dojo

Expected/desired behavior

The selection of the items should be correctly changed when typing, even if a delay different than 0 is configured.
Also, it should be possible to change the selected item by typing in the keyboard even if the filter option is set and the DropDownList is closed.

Environment

• Kendo UI version: 2021.1.224
• Browser: [all]

Add a filterOptions option that will enable users to configure attributes, placeholder, etc for the search box of the DropDownList. 

I have upgraded a huge project we have, from Kendo UI 2017 to the latest version.
I managed to fix all the incompatibility issues that I had with the latest version and now it's ready to go live.

In the final regression tests our customer found a bug and now we are stack and cannot deploy the project.

Here is the problem:

In the DropdownList, if you type something and then press the clear button, the change event is firing two times. One with the value that you typed before and then one again with an empty value (the right one). The biggest problem is that there is no way to determine that the first event is coming from the clear button and not from the user, so I cannot find any workaround this.

I searched and I found that this started after this change.

You can check this dojo for a reproduction of the problem.
Steps:
Type "it" in the dropdownlist,
Wait for the items to popup
Don't select any item but press the clear button of the dropdownlist
You can see the attached image the wrong events.
If you select a version after 2019 R3, the change event is firing twice. If you select an older version the change event is not firing at all.

I can understand a change event with an empty value and I don't have any problem with that, but the first event is totally wrong.
Is there any quick solution to this so we can catch the deadline and deploy the new version of our project?

Thank you for your time,
John Dendrinos

Reproduction of the problem

1. Run this dojo
2. Enter "123" - the popup container with the list of items is displayed below the DropDown element
3. Enter "1234" - the popup container with the list of items is displayed above the DropDown element when sufficient space is available below the element
4. Enter "12345" - the NoDataTemplate is displayed above the DropDown element when sufficient space is available below the element

Expected/desired behavior

The popup container with the list of items should be displayed below the DropDown element when sufficient space is available below the element

Environment

• Kendo UI version: 2020.1.406

I am using a DropDownList with dynamic items that are grouped.

When opening the dropdown without items in the datasource the fixed group header is displayed empty.

When removing the last item from the datasource after the DropDown has already been opened, the first group header is still displayed when opening the dropdown.

I would expect the group header to never be displayed if there is no data.

See Dojo: https://dojo.telerik.com/EviPepIJ

Hello,

Drop down widget is defaulted to first option even though ng-model is undefined, in case where we bind same value to k-data-value-field and k-data-text-field.

Please have a look on the below sample code where you can find issue. My expectation is drop down should not default when model value is not assigned.
