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.

https://dojo.telerik.com/iliKAqUr

  1. select "Oranges" from the dropdown
  2. press "Change value to 'Bananas'" button
  3. press "Sort" button
  4. 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:

  1. https://demos.telerik.com/kendo-ui/combobox/grouping
  2. https://demos.telerik.com/kendo-ui/dropdownlist/grouping
  3. 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

  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

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.

Check out this idea. It may help solve this issue and help with UI presentation.

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

It will be very nice if the AutoComplete, DropDownList, ComboBox, and MultiSelect components have the floating label functionality like the TextBox widget

Bug report

Reproduction of the problem

Dojo example

  1. Inspect the value in the pre tag above the DropDownList and the selected value in the DropDownList.

Current behavior

The model has the extra spaces trimmed and there is a single space between the words:

<pre class="ng-binding">Magazzini Alimentari Riuniti</pre>

In the DropDownList the value properly contains 2 spaces between the words.

Expected/desired behavior

In the data the selected item has 2 spaces between the words: Magazzini Alimentari Riuniti
The model value should be identical to the data and the extra spaces should not be trimmed.

When there is no filter enabled in the DropDownList it is possible to select an item just by typing, without opening the DropDownList popup.

https://dojo.telerik.com/ELEfIZIx

It would be useful if such an option is available when the filter of the widget is configured.

Bug report

When filtering the DropDownList data when a limited amount of items remain the popup container is displayed above the DropDown element when sufficient space is available below the element

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

Bug report

The change event is being triggered when having an initially selected item in the DropDownList and then open the DropDownList and click on the default selected item. This bug is represented only in MVVM.

Reproduction of the problem

  1. Open this Dojo and run it. The three cascading DropDownLists will have default selected items
  2. Click on the first DropDownList and select the already selected "Confections" option
  3. The other two DropDownLists will be reset because of the change event thrown in the first DropDownList

Current behavior

The change event of a DropDownList with initial data selected is being triggered when clicking on the already selected value.

Expected/desired behavior

Selecting the already selected item of a DropDownList shouldn't trigger its change event because there is no actual change in the component's value. Please check this Dojo for the expected behavior.

Release 2020.R2

In the DropDownList and ComboBox, virtualization only works when the popup is open. In both widgets, item navigation is functional by pressing down to select the next item in the list without opening the popup. However, when the end of the first page of results is reached, the selection goes back to the top of the first page of results instead of loading the second page via virtualization. This misleads the user in that it only presents a portion of the options available. This is also an issue for disabled users and accessibility.

https://demos.telerik.com/kendo-ui/dropdownlist/virtualization

https://demos.telerik.com/kendo-ui/combobox/virtualization

In both examples, holding down without opening the popup will never load more results.

We have had this issue in the past but it is a bigger issue now that we are focusing more on accessibility since users rely more heavily on keyboard navigation.

the multiselect control should have the possibility to define elements as not editable (readonly) so that those elements can not be removed while other elements can be removed or new elements can be added.

When the user enters a filter, the list is filtered. But if the user deletes the filter by clicking on the X in the filter box, the list remains filtered. It does not revert to the full, unfiltered list. 

To get back to the full list, the user must delete the filter by backspacing or pressing the delete key on the keyboard.

This behavior is confusing some users, who have used the mouse to delete the filter in IE11.  There's no longer a filter string there, but the list is still filtered.

Can  the dropdownlist listen for the click that clears the filter string from the textbox?
