Selection and Nesting in React ButtonGroup component

22 Jul 2021 / 3 minutes to read

Selection

Single selection

ButtonGroup supports radio type selection in which only one button can be selected. This can be achieved by adding input element along with id attribute with its corresponding label along with htmlFor attribute inside the target element. In this ButtonGroup, the type of the input element should be radio and e-btn is added to the label element.

The following example illustrates the single selection behavior in ButtonGroup.

Multiple selection

ButtonGroup supports checkbox type selection in which multiple button can be selected. This can be achieved by adding input element along with id attribute with its corresponding label along with htmlFor attribute inside the target element. In this ButtonGroup, the type of the input element should be checkbox and e-btn is added to the label element.

The following example illustrates the multiple selection behavior in ButtonGroup.

Nesting

Nesting with other components can be possible in ButtonGroup. The following components can be nested in ButtonGroup,

  • DropDownButton
  • SplitButton

For nesting support, SplitButton dependencies should be configured and it should be added in system.config.js.

To initialize DropDownButton component, refer DropDownButton Getting Started documentation.

In the following example, DropDownButton component is added in src/App.tsx by importing it from ej2-react-splitbuttons.

// To render ButtonGroup with DropDownButton nesting.
class App extends React.Component<{}, {}> {
  public items: ItemModel[] = [
{
    text: 'Learn SQL'
},
{
    text: 'Learn PHP'

{
    text: 'Learn Bootstrap'

    </div>
  </div>
