MultiSelect provides the option to display grouped data inside the component. The current article discusses the following MultiSelect 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
To configure the data grouping in the MultiSelect component you need to define the
groupFieldproperty sets the fields that defines the group name in each data item.
The MultiSelect doesn't internally group the data passed to it. To use the component in a grouping scenario, you need to use the
groupBymethod available in the KendoReact DataQuery package.
The following example demonstrates the MultiSelect data grouping in action.
Grouping with Filtering
The following example demonstrates how to configure the MultiSelect in a Grouping + Filtering scenario.
Using the itemRender, groupHeaderItemRender, and groupStickyHeaderItemRender of the KendoReact MultiSelect component we can customize its
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 MultiSelect data the way your scenario needs it.
