Appearance

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

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

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

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

Options

The Kendo UI MultiColumnComboBox supports the following styling options:

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

Size

The size option controls how big or small the MultiColumnComboBox 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="multicolumncombobox" />
<script>
    $("#multicolumncombobox").kendoMultiColumnComboBox({
      size: "large",
      dataSource: [
        { id: 1, name: "Apples" },
        { id: 2, name: "Oranges" }
      ],
      columns: [
            { field: "name" },
            { field: "id" }
      ],
      dataTextField: "name",
      dataValueField: "id",
    });
</script>

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

<span class="k-input k-combobox k-widget k-dropdowngrid k-combobox-clearable k-input-outline k-input-lg k-rounded-full">
</span>

Rounded

The rounded option controls how much border radius is applied to 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 full and it is applied to the span.k-combobox wrapping element that contains the whole HTML through the k-rounded-full class.

The example below shows a basic MultiColumnComboBox configuration and how to set rounded to "medium":

<input id="multicolumncombobox" />
<script>
    $("#multicolumncombobox").kendoMultiColumnComboBox({
      rounded: "medium",
      dataSource: [
        { id: 1, name: "Apples" },
        { id: 2, name: "Oranges" }
      ],
      columns: [
            { field: "name" },
            { field: "id" }
      ],
      dataTextField: "name",
      dataValueField: "id",
    });
</script>

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

<span class="k-input k-combobox k-widget k-dropdowngrid k-combobox-clearable k-input-outline k-input-lg k-rounded-md">
    ...
</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-combobox wrapping element through the k-input-solid class.

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

<input id="multicolumncombobox" />
<script>
    $("#multicolumncombobox").kendoMultiColumnComboBox({
      fillMode: "outline",
      dataSource: [
        { id: 1, name: "Apples" },
        { id: 2, name: "Oranges" }
      ],
      columns: [
            { field: "name" },
            { field: "id" }
      ],
      dataTextField: "name",
      dataValueField: "id",
    });
</script>

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

<span class="k-input k-combobox k-widget k-dropdowngrid k-combobox-clearable k-input-outline k-input-medium k-rounded-full">
</span>

Old vs New Rendering

Below you will find the differences between the old and the new rendering. Some of the HTML elements rendered before are replaced with others in the new rendering.

Old Wrapper 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.
