/**
 * A split button component.
 *
 * The main content of the button and the handler of the main click event is specified by
 * using a `<gtx-split-button-primary-action>` child element.
 *
 * Secondary actions can be defined using `<gtx-dropdown-item>` child elements and
 * their click handlers. If secondary actions are defined, a dropdown trigger
 * will be displayed to the right of the main content.
 *
 * All input properties of `<gtx-button>`, except for `icon` and `submit` are supported.
 *
 * This component depends on the `<gtx-overlay-host>` being present in the app.
 *
 * ```html
 * <gtx-split-button>
 *     <gtx-split-button-primary-action (click)="save()">Save Document</gtx-split-button-primary-action>
 *     <gtx-dropdown-item (click)="saveAndPublish()">Save and Publish</gtx-dropdown-item>
 *     <gtx-dropdown-item (click)="saveAndEmail()">Save and Send via E-Mail</gtx-dropdown-item>
