Grouping

The KendoReact MultiColumnComboBox provides the option to display grouped data inside the component. The current article discusses the following MultiColumnComboBox Grouping scenarios:

• Basic usage and differences between the two grouping modes available for the component
• Grouping with filtering
• Customization of the different popup elements when working with grouped data

Basic Usage

To configure the data grouping in the MultiColumnComboBox component you need to define the groupField and groupMode properties.

• The groupField property sets the fields that defines the group name in each data item.
• The groupMode property determines the way the grouped data will be rendered inside the component's popup. The available groping mode are modern and classic.

The MultiColumnComboBox doesn't internally group the data passed to it. To use the component in a grouping scenario, you need to use the groupBy method available in the KendoReact DataQuery package.

The following example demonstrates the modern grouping mode in action.

Grouping with Filtering

The following example demonstrates how to configure the MultiColumnComboBox in a Grouping + Filtering scenario.

Grouping Customization

Using the itemRender, groupHeaderItemRender, and groupStickyHeaderItemRender of the KendoReact MultiColumnComboBox component we can customize its data items, group headers, and the 'sticky' header that displays the top-most group that is currently being scrolled.

By customizing the templates passed to each of the listed above properties you can modify the grouped MultiColumnComboBox data the way your scenario needs it.
