/**
 * @class
 *
 * ### Overview
 *
 * The `ui5-menu-item-group` component represents a group of items designed for use inside a `ui5-menu`.
 * Items belonging to the same group should be wrapped by a `ui5-menu-item-group`.
 * Each group can have an `checkMode` property, which defines the check mode for the items within the group.
 * The possible values for `checkMode` are:
 * - 'None' (default) - no items can be checked
 * - 'Single' - Only one item can be checked at a time
 * - 'Multiple' - Multiple items can be checked simultaneously
 *
 * **Note:** If the `checkMode` property is set to 'Single', only one item can remain checked at any given time.
 * If multiple items are marked as checked, the last checked item will take precedence.
 *
 * ### Usage
 *
 * `ui5-menu-item-group` represents a collection of `ui5-menu-item` components that can have the same check mode.
 * The items are addeed to the group's `items` slot.
 *
 * ### ES6 Module Import
 *
 * `import "@ui5/webcomponents/dist/MenuItemGroup.js";`
 * @constructor
 * @extends UI5Element
 * @implements {IMenuItem}
