Appearance

As of Kendo UI R1 2022, the jQuery DropDownList widget has new rendering and styling options.

In this article, you will find information about the rendering of the Kendo UI DropDownList.

For additional information regarding the decision behind these changes, visit the Styling Overview article.

For a live example, visit the Appearance Demo of the DropDownList.

Options

The Kendo UI DropDownList supports the following styling options:

size—configures the overall size of the component.
rounded—configures the border radius for the tags.
fillMode—controls how the color is applied.

Size

The size option controls how big or small the DropDownList component looks. The structure of the class is k-picker-{size}.

The following values are available for the size option:

sm—small size
md—medium size
lg—large size
none—unset

The default size value is medium and it is applied to the span wrapping element through the k-picker-md class.

The example below shows a basic configuration and how to set size to "large":

<input id="dropdownlist" />
<script>
    $("#dropdownlist").kendoDropDownList({
      size: "large"
    });
</script>

Below is the HTML that is affected from the configuration. The changes are applied to the span.k-dropdownlist wrapping element:

<span class="k-dropdownlist k-picker k-picker-lg">
    ...
</span>

Rounded

The rounded option controls how much border radius is applied to the tags for the selected items in the widget. The structure of the class is k-rounded-{size}.

The following values are available for the rounded option:

sm—small border radius
md—medium border radius
lg—large border radius
full—ellipse-like border radius
none—unset

The default value is medium and it is applied to the span.k-dropdownlist wrapping element through the k-rounded-md class.

The example below shows a basic DropDownList configuration and how to set rounded to "full":

<input id="dropdownlist" />
<script>
    $("#dropdownlist").kendoDropDownList({
      rounded: "full"
    });
</script>

The changes are applied to the span.k-dropdownlist wrapping element:

<span class="k-dropdownlist k-picker k-rounded-full">
    ...
</span>

FillMode

The fillMode option controls how the color is applied. The structure of the class is k-picker-{fillMode}.

The following values are available for the fillMode option:

solid
flat
outline
none

The default value is solid and it is applied to the span.k-dropdownlist wrapping element through the k-picker-solid class.

The example below shows a basic DropDownList configuration and how to set fillMode to "outline":

<input id="dropdownlist" />
<script>
    $("#dropdownlist").kendoDropDownList({
      fillMode: "outline"
    });
</script>

The changes are applied to the span.k-dropdownlist wrapping element:

<span class="k-dropdownlist k-picker k-picker-outline">
    ...
</span>

Old vs New Rendering

The old rendering of the component consisted of several wrapping elements:

The outer span wrapper with the k-dropdown and k-widget classes.
```


```

The inner span wrapper with the k-dropdown-wrap class.

<span class="k-dropdown-wrap k-state-default">
</span>

The input element with the k-input class. This element is a child of the k-dropdown-wrap span.
```
<input class="k-input" role="combobox" >

```
The button span element with k-select class. This element is a child of the k-dropdown-wrap span and renders the button which expands the dropdown on click.
```


```
The icon span element with the k-icon class. This element is a child of the k-select span and renders the dropdown arrow icon.
```

```

The new rendering of the component consists of a single wrapping span element that contains the child input and button elements:

The span element controls the overall appearance of the widget and has the following class structure:
```


```
The span element controls the appearance of the DropDownList itself and has the following class structure:
```

```

The button element controls the appearance of the button that expands the dropdown popup and has the following class structure:

<button type="button" class="k-select k-input-button k-button k-icon-button k-button-md k-button-solid k-button-solid-base k-icon-button">
</button>

The inner span element renders the dropdown arrow icon of the DropDownList and has the following class structure:
```

```

With the previous versions, when the filtering was enabled, the search icon in the DropDownList popup was rendered on the right side. With the new rendering, the search icon is rendered on the left side.

The examples below demonstrates the full version of the old and new rendering:

Wrapper Rendering:

<!-- OLD WRAPPER-->

    </span>
    <button class="k-select k-input-button k-button k-button-md k-rounded-md k-button-solid k-button-solid-base k-icon-button">

Visual Backwards Compatibility

To achieve the same look and feel as the old rendering, you must update the element references.

When you use a LESS theme, the new styling and rendering supports only the default options.

Previously, a reference to the DropDownList input element was obtainable through the k-input class.

$(".k-input") // Returns a reference to the input element in the old rendering.

With the new rendering, you must target the DropDownList input element by using the k-input-inner class.

$('.k-dropdownlist .k-input-inner') // Returns a reference to the input element in the new rendering.

Previously, a reference to the dropdown button element was obtainable through the k-select class.

$(".k-select") // Returns a reference to the dropdown button element in the old rendering.

With the new rendering, you can obtain a reference to the dropdown button element through the k-button and k-input-button classes.

$(".k-button") // Returns a reference to the dropdown button element in the new rendering.
$(".k-input-button") // Returns a reference to the dropdown button element in the new rendering.

Previously, a reference to the items in the DropDownList popup was obtainable through the k-item class.

$(".k-item") // Returns a reference to the items rendered in the DropDownList popup.

With the new rendering, the DropDownList item elements must be targeted by using the k-list-item class.

$('.k-list-item') // Returns a reference to the items rendered in the DropDownList popup.

The following example showcases how to customize the styles of the DropDownList in both the new, and the old rendering:

    <!-- Open the example in Dojo and select version prior to 2022 R1 to see the difference in the appearance -->
    <input id="products" style="width: 100%" />
    <script>
      var dataSource = new kendo.data.DataSource({
        transport: {
          read: {
            url: "https://demos.telerik.com/kendo-ui/service/products",
            dataType: "jsonp"
          }
        }
      });
      $("#products").kendoDropDownList({
        dataSource: dataSource,
        dataTextField: "ProductName",
        dataValueField: "ProductID",         
        value: [5]
      });

    </script>
    <style>
      /*  NEW RENDERING */
      /*  The style below will works with versions R1 2022 and later*/ 

      .k-dropdownlist .k-input-inner{ /* customize the style input */
        background: lightgreen;
      }

      .k-list-item{ /* customize the styles of the items in the popup */
        background-color: #FFDFDD;
      }    

      #products_list .k-selected{ /* applies orange background and border to the selected item in the popup */
        background-color: #FBBBB9;
        border: 2px solid #E56E94;
      }   

      /*  OLD RENDERING */
      /*  The style below will works with versions prior to R1 2022 */ 


      #products-list .k-item{ /* customize the styles of the items in the popup */
        background-color: #FFE5B4 !important;
      }

      #products-list .k-state-selected{ /* customize the styles of the selected items in the popup */      
        border: 2px solid orange !important;
        color: brown !important;
      }

      #products-list .k-state-selected:hover{ /* customize the styles of the selected items in the popup */
        background-color: orange !important;
        color: white !important;
      }
    </style>

With the new rendering different classes should be used in order to customize the DropDownList templates.

    <!-- Open the example in Dojo and select version prior to 2022 R1 to see the difference in the appearance -->
    <input id="customers" style="width: 100%" />
    <script>
      $(document).ready(function() {
        $("#customers").kendoDropDownList({          
          dataTextField: "ContactName", 
          dataValueField: "CustomerID",
          groupTemplate: "Group template: #: data #",
          fixedGroupTemplate: "Fixed header: #: data #",
          footerTemplate: 'Total <strong>#: instance.dataSource.total() #</strong> items found',
          noDataTemplate: 'No Data!',
          height: 400,
          filter: 'contains',
          dataSource: {
            type: "odata",
            transport: {
              read: "https://demos.telerik.com/kendo-ui/service/Northwind.svc/Customers"
            },
            group: { field: "Country" }
          }
        });
      });
    </script>
    <style>

      /*  NEW RENDERING */
      /*  The styles below will work with versions R1 2022 or later*/ 

      /*customize groupTemplate */
      #customers-list .k-list-item-group-label{
        background: blue !important;
        color: yellow !important;
        font-size: 18px;
      }

      /*customize fixedGroupTemplate */
      #customers-list .k-list-group-sticky-header{
        background: turquoise !important;
      }

      /*customize footerTemplate */
      #customers-list .k-list-footer{
        background: darkCyan !important;
        color: white;
      }

      /*customize nodataTemplate */
      #customers-list .k-no-data{
        color: green !important;
        font-weight: bold;
      }

      /*  OLD RENDERING */
      /*  The styles below will work with versions prior to R1 2022 */ 

      /*customize groupTemplate */
      #customers-list .k-item>.k-group{
        background: red !important;
        color: white !important;
      }

      /*customize fixedGroupTemplate */
      #customers-list .k-group-header{
        background: salmon !important;
      }

      /*customize footerTemplate */
      #customers-list .k-footer{
        background: tomato !important;
        color: white;
      }

      /*customize nodataTemplate */
      #customers-list .k-nodata{        
        color: red;
