TL;DR: The DropDownList widget cannot be closed by clicking the arrow-icon.
The long story:
After the DropDownList has been opened once, it closes and reopens every time the user clicks the arrow-icon. Closing the DropDownList still works when clicking anywhere on the dropDown except the arrow-icon (or rather the button around it) or anywhere else but the dropDown. This DOJO demonstrates the problem. Animations have been disabled to allow easier reproduction (with animations on, the problem appears only occasionally, probably because of timing issues).
If you look closely, you will notice that the dropDown closes when the mouse button is pressed and reopens when the mouse button is released (this is when the click event is fired). Therefore, the problem can be (temporarily) mitigated by suppressing the mousedown event on the dropDown's wrapper element.
After updating the version of Kendo we are using to 2022.1.412 we noticed a weird behavior in the DropDownLists. Clicking the drop down arrow once opens the list, then clicking the arrow again closes and re-opens the list instead of just closing it. Note that this does not happen while clicking on any other part of the drop down to close it, selecting an item from the drop down, or clicking outside the drop down list. It only happens while clicking on the arrow button.
Behavior can be seen in the demos on these pages:
https://demos.telerik.com/kendo-ui/dropdownlist/template
https://demos.telerik.com/kendo-ui/dropdownlist/grouping
https://demos.telerik.com/kendo-ui/dropdownlist/cascadingdropdownlist
However the behavior does not appear on these pages:
https://demos.telerik.com/kendo-ui/dropdownlist/virtualization
https://demos.telerik.com/kendo-ui/dropdownlist/serverfiltering
Steps to Reproduce:
- Click the drop down arrow to open the drop down list
- Click on the arrow again and observe the list close and re-open (Note it sometimes doesn't happen right away but takes a few tries)
Describe the bug
While the loading icon is visible in the DropDownList when fetching data, the widget's height is changed.
To reproduce
- Open this Dojo example - https://dojo.telerik.com/AFuQItIv/4
- 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.

As my grid edit forms have expanded past the default popup, I have been using editable template. These are bound with MVVM and work well. But not all options work via MVVM like the cascade options below. I would like to use the cascade options in this scenario. It would be great to have all configuration options available via MVVM.
<select id="ParentID" name="ParentID"style="width: 100%"
data-role="dropdownlist"
data-text-field="Name"
data-value-field="ID"
data-cascade-from="ImprovementTargetID"
data-cascade-from-field="ImprovementTargetID"
data-cascade-from-parent-field="ID"
data-source="PEDropDownDataSource"
data-option-label="Pick PE..."
data-value-primitive="true"
data-bind="value:ParentID">
</select>
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.

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
The height of the DropDownList popup is incorrect when using LESS themes.
Reproduction of the problem
- Open this Dojo example - https://dojo.telerik.com/@martin.tabakov@progress.com/oMohisUF/2
- Open the DropDownList
Current behavior
The popup height is incorrect.
Expected/desired behavior
The popup height should be big enough to fit the list.
Environment
- Kendo UI version: 2022.1.119
- Browser: [all]
Bug report
When filtering is performed in the parent widget and an item is selected, duplicate read request are sent to the remote end point for the child widget data.
Reproduction of the problem
- Open the Dojo
- In the parent DropDownList search "be" and select "Beverages"
Current behavior
Two requests are sent to the 'Products' DropDownList read end point.
Expected/desired behavior
There should be a single request for reading the widget`s data.
The issue is a regression since 2019 R3 SP1 (2019.3.1023)
Environment
- Kendo UI version: 2021.3.1109
- Browser: [all ]
The Kendo UI DropDownList allows the user to entera filter which is applied on the available items (documented here: https://docs.telerik.com/kendo-ui/api/javascript/ui/dropdownlist/configuration/filter). As soon as a filter term entered by the user is applied to the dataSource, the selected item is no longer marked. Usually, the .k-state-selected CSS class is set on the corresponding DOM element.
This behavior can also be reproduced in the official Kendo UI Dojo about filtering: https://dojo.telerik.com/eVuSopuj
It will be very nice if the AutoComplete, DropDownList, ComboBox, and MultiSelect components have the floating label functionality like the TextBox widget
Bug report
In a virtual DropDownList with a value set, the first item is marked as selected as well. The issue occurs when using jQuery 3.4.1 or later.
Reproduction of the problem
- Open this Dojo example. - https://dojo.telerik.com/@martin.tabakov@progress.com/UkOmiYEj
- Open the DropDownList.
Current behavior
Two items are marked as selected.
Expected/desired behavior
Only the item with value 3 should appear as selected.
Environment
- Kendo UI version: 2021.3.914
- **jQuery version: 3.4.1 and later

A kendoDropDownList places an arrow to the right of the <select/> element, indicating it's a dropdown (.k-i-arrow-s). It would be cool if kendoMultISelect did the same thing. Clicking the <select/> element or the arrow should also toggle the visibility on the list items. See http://stackoverflow.com/questions/31825788/kendo-multiselect-to-have-arrow-icon-and-behavior-to-close-on-click .
https://dojo.telerik.com/iliKAqUr
- select "Oranges" from the dropdown
- press "Change value to 'Bananas'" button
- press "Sort" button
- select "Oranges" from the dropdown
Expected: should see two events for "Changed to Oranges" but only see one
Actual: status only shows one value change event from the first selection of "Oranges"
It seems this issue was introduced with the fix for https://github.com/telerik/kendo-ui-core/issues/4496
The introduction of _oldText in the _change method of kendo.list.js has introduced a flaw in the value change detection for DropDownList
The above dojo presents a way to short-circuit the issue since it is not easy to show the _oldText issue since the index check works as a fallback.
In Combox, DropDownList, Multiselect widgets, when grouping, the first item is incorrectly rendered (inconsistently with the others).
This can be observed as of today on:
- https://demos.telerik.com/kendo-ui/combobox/grouping
- https://demos.telerik.com/kendo-ui/dropdownlist/grouping
- https://demos.telerik.com/kendo-ui/multiselect/grouping
Additionaly, when groupTemplate is defined, it's ignored for the first item: https://docs.telerik.com/kendo-ui/api/javascript/ui/dropdownlist/configuration/grouptemplate

Thank you for your kind reply.
I saw the link you sent me.(https://dojo.telerik.com/eHUBOtOW/2)
When a Korean keyword is searched, the cursor is pushed back.
It works fine in Chrome, but the same thing happens in IE.
Our company's system have to use IE.
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
- On a Macbook Pro set the trackpad click to light
- Run this dojo
- 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
- Open the Demo
- Focus/Open the DropDownList
- Click 's' - Small is selected
- Click 'l' - Large is selected
- 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.
