Hi,

At present, the DropDowns have the capability to accommodate just a single level of grouping. Enhancing this feature to support multiple levels of grouping would be highly beneficial.

Hi,

At present, the DropDown components do not activate their popups when focused and the spacebar is pressed. Instead, the popup opening is achieved by pressing "alt + arrowDown." However, to align with the behavior of HTML5 select elements, it would be expected that the Kendo DropDown components open their popups when the spacebar is pressed as well.

Hi,

The defaultItem should be modified to accept null values and, when valuePrimitive is set to false, display them as empty options.

Example with the select element - https://stackblitz.com/edit/stackblitz-starters-9ftiew?file=src%2Fmain.ts

Greetings,

My team and I are wondering about the possibility for the DropDownLists to be configurable to allow screenreader users to focus disabled items in the dropdown list.

Currently in the DropDownList, it is not possible (or we can't discover) to reach disabled items in a DropDownList (not talking about the input itself being disabled, but rather items inside)

https://www.telerik.com/kendo-angular-ui/components/dropdowns/dropdownlist/disabled-items/

Regardless of if this functionality does or does not violate any accessibility standards, we believe it would be a useful feature for screen reader users. We are also aware that the default HTML select does skip disabled options:

https://developer.mozilla.org/en-US/docs/Web/HTML/Element/select#advanced_select_with_multiple_features

There is precedent for this behavior in drop down lists from other vendors:

https://ng-bootstrap.github.io/#/components/dropdown/examples#disabled

https://github.com/JedWatson/react-select/issues/3354

Other relevant discussions:

https://github.com/nvaccess/nvda/issues/14190

Perhaps adding a simple [disabledItemsFocusable]="false" boolean (false by default for backwards compatibility) to the inputs could be a solution here.

Greetings

Related to this issue, when you use multiple groups, then the header of the first subgroup doesn't get rendered. This cascades down all sublevels.
Example: https://codesandbox.io/s/strange-benji-3m9d19?file=/src/app/app.component.ts 

As I was typing this up I also noticed that we don't have access to the field we're grouping on in the kendoDropDownListGroupTemplate (not exclusive to the DropDownList, all dropdown types have this problem).

It'd be great and a very minor change to enable this.
It's currently like this (line 103 inside common/list.component.ts in the source code): 

[templateContext]="{
    templateRef: groupTemplate.templateRef,
    $implicit: dataItem.value
}"

[templateContext]="{
    templateRef: groupTemplate.templateRef,
    $implicit: dataItem.value,
    field: dataItem.field
}"

Regards

I'm using the Kendo Angular DropDownList component and I'm facing a couple of accessibility issues.

I got two issues, the same as those I get in my own application using the DropDownList component.
I've attached the output for both issues below.

First issue and an explanation of the issue and its solutions can be seen in the first attachment.

Second issue and an explanation of the issue and its solutions can be seen in the sercond attachment.

Hi,

I have a list of objects whose text field may contain accented characters. For example: Raúl, Úrsula, José.

I'd like to keep the display of those names with their accents, but when applying the filter they should be treated as their non-accented counterpart.

So, if in the list there is a Raúl and a Raul, typing 'rau' in the filter both should appear.

An option in DropDownFilterSettings similar to the caseSensitive one would be much appreciated.

Thanks,

Stefano

1.) Use grouping functionality for the drop list's data.

2.) Have at least one item disabled. (Easiest to replicate if the first item is disabled)

3.) Click on dropdown to open the popup.

4.) If first item is disabled notice the group it belongs to is not displayed in the popup. If the first item isn't disabled scroll until disabled item is at the top of the list and the group information will be cleared.

Easily replicated if you modify the stackblitz from this page https://www.telerik.com/kendo-angular-ui/components/dropdowns/dropdownlist/grouping/ to disable the first item in the list

"Meat" should be displayed in that empty row at the top. Lines 12 and 26-28 are the only modifications made to the code found at the url above.

Please provide a filed or other public property that allows to track the currently focused item for the DropDowns.

Thank you

Hello,

we want to show filtered data in the options list of the dropdown component and request a feature, to provide a filter callback function or the possiblity to pass different data sources to the component.

The use case is, that the dropdown should show existing values but when opening the dropdown list, the user should only be able to select a subset of the data source. Yes there is the possibility to disable items, but we want to complete hide them as a choice.

Currently we apply the workaround to filter the data on the open event and reset the data on the close event but we think, that this can be a common feature for the dropdown list.

Thank you!

Can we update the dropdownlist control to allow for a filter region template. This will allow, so that a custom component can be placed where the filter box is.

The use case that we have is to have our common input component, which has all the application styles pre-applied, be used for filtering. We can currently do this for grid component's filtering. But unlike grid filters, kendo dropdownlist does not allow for a template for the search region. This would be a good feature and consistent with other controls in the kendo library.

Placeholder for dropdownlist could be a great thing, because defaultItem not have the same use. I just want to show text when nothing is select, but I do not want that the dropdownlist have nothing selected (or the defaultItem) when we have already selected an item. The defaultItem can be selected again and it is not the same use of placeholder.

Thanks for reading.

In the example below "X-Small" is initially the selected item in the dropdown.  Once you click the "Sort" button and sort the array, "2X-Large" becomes the highlighted item in the dropdown but "X-Small" is displayed.  I would expect that "X-Small" would be highlighted.  After opening and closing the dropdown "2x-Large" becomes the selected item even if you don't select it.  The same behavior does not happen with a simple select dropdown.

import { Component, OnInit } from '@angular/core';

@Component({
  selector: 'my-app',
  template: `
  <form>
    <div>
      <p>T-shirt size:</p>
      <kendo-dropdownlist [data]="listItems" [(ngModel)]="selectedShirt" name="shirtsize">
      </kendo-dropdownlist>
    </div>
    <br/>
    <div>
    <select [(ngModel)]="selectedShirt" name="shirtsize2">
      <option *ngFor="let d of listItems">{{d}}</option>
    </select>
    </div>
    <br/>
    <button (click)="sortArray()">Sort</button>
  </form>
  `
})
export class AppComponent implements OnInit {
    public listItems: Array<string> = ["X-Small", "Small", "Medium", "Large", "X-Large", "2X-Large"];
    public selectedShirt: string;
    ngOnInit(){
      this.selectedShirt = this.listItems[0];
    }

    sortArray(){
      this.listItems.sort((a, b) => a.localeCompare(b));
    }
}

Is there any way to set error focus on the selected items in multi select component.
And after that, user can take immediate action to update the value, say auto Open the drop down dialog and go to the selected item.

The desired feature is partially implemented for single selection only and with no functionality on the nested grid.We would like a multiselect DropDown box with searching functionality and when clicked to make a selection, a grid will be displayed with sorting, searching, pagination and filtering functionality.We strongly believe that this kind of functionality is necessary for enterprise grade applications with complex forms.
Thanks in advance.

Can we have the MultiColumnComboBox (already available in Kendo UI JQuery) in Angular 2+ please..

find below appcomponent.html code: <kendo-dropdownlist [defaultItem]="defaultYear"
 [data]="budgetYears"
[valueField]="budgetYears.value">
</kendo-dropdownlist>

and in appcomponent.ts file:
public budgetYears: Array<{ value: number }> = [
        { value: 2019 },
        { value: 2020 },
        { value: 2021 },
        { value: 2022 },
        { value: 2023 },
        { value: 2024 },
    ];

as mentioned above I have provided the mentioned codes but I am not getting the binded values. Instead of that I am getting [object Object]. Why it is so and where I am doing mistake. Please provide me a solution for this. Thanks
