To enable this behavior for a particular item, set its HamburgerSubMenuNavigationButton.ShowInPreview property to true.

xmlns:Layout="using:DevExpress.UI.Xaml.Layout"

<Layout:HamburgerSubMenu.Items>
    <Layout:HamburgerSubMenuNavigationButton Content="Outbox" RightContent="12" NavigationTargetType="local:HamburgerMenuDemo_OutboxPage"/>
    <Layout:HamburgerSubMenuNavigationButton Content="Inbox" RightContent="142" ShowInPreview="True" NavigationTargetType="local:HamburgerMenuDemo_InboxPage"/>

</Layout:HamburgerSubMenu.Items>

By default, the MoreButtonVisibilityMode property is set to Auto. In this mode, the More predefined button is automatically displayed if not all items are shown in the preview. With a click on this button, a sub-menu fly-out panel that contain all sub-menu items opens.

Set this property to Hidden or Visible to explicitly specify the More button’s visibility.
