Appearance

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

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

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

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

Options

The Kendo UI AutoComplete 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 AutoComplete component looks. The structure of the class is k-input-{size}.

The following values are available for the size option:

  • sm—small size
  • md—medium size
  • lg—large size

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

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

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

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

<span class="k-autocomplete k-input k-input-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

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

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

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

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

<span class="k-autocomplete k-input k-rounded-full">
    ...    
</span>

FillMode

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

The following values are available for the fillMode option:

  • solid
  • flat
  • outline

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

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

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

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

<span class="k-autocomplete k-input k-input-outline">
    ...    
</span>

Old vs New Rendering

Visual Backwards Compatibility

In order to achieve the same look and feel as the old rendering, the element references must be updated. Visit the CSS Classes Migration and JQuery Selectors Migration sections of the Styling Overview article for additional information.

The new styling and rendering supports only the default options when you use a LESS theme.

Previously, a reference to the AutoComplete 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, the AutoComplete input element must be targeted by using the k-input-inner class.

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

The AutoComplete also provides options for setting the widths of its list and popup, accessing its list elements, and removing its input value.

Setting the List Width

To customize the width of the AutoComplete list and change its dimensions, use the jQuery width() method.

<input id="autoComplete" />

<script>
    $("#autoComplete").kendoAutoComplete();
    var autoComplete = $("#autocomplete").data("kendoAutoComplete");
    // Set the width of the drop-down list.
    autoComplete.list.width(400);
</script>

Setting the Popup Width

You can enable the popup element to automatically adjust its width according to the length of the item label it displays. When the autoWidth option is set to true, the popup will display the content on a single line and will not wrap it up.

<input id="autocomplete" style="width: 100px;" />
<script>
$("#autocomplete").kendoAutoComplete({
  autoWidth: true,
  dataSource: {
    data: ["Short item", "An item with really, really long text"]
  }
});
</script>

Accessing list Elements

The AutoComplete list renders an ID attribute which is generated from the ID of the widget and the -list suffix. You can use the ID to style the element or to access a specific element inside the popup element.

If the AutoComplete has no ID, the list element will have no ID either.

<input id="autocomplete">
<script>
  $(document).ready(function() {
    $("#autocomplete").kendoAutoComplete({
        dataSource: ["Item1", "Item2"]
    });

    // The DIV popup element that holds the header and footer templates, and the suggestion options.
    var popupElement = $("#autocomplete-list");

    console.log(popupElement);
  });
</script>

Removing Input Values

The AutoComplete enables you to remove the values from its input area by using the clearButton configuration option. As a result, an X button appears in the input area on hover and when clicked, it resets the value of the widget and triggers the change event. By default, clearButton is enabled and is set to true.
