SplitButton groups a collection of menu items in an overlay with a default command button. This button uses a common menu model API to define its items. Hence, the split button is a combination of button and menu components. A basic example of SplitButton component with defined label text would be written as follows:

<p-splitButton label="Create" (onClick)="create()" [model]="items">
</p-splitButton>

The label is applied only for the default command button. The following screenshot shows a snapshot result of the split button example:

The split button component supports one event callback named onClick, which will be invoked on the click of the default button element.
