    }
</style>

<DxButton Text="Show Context Menu" 
          Click="() => ContextMenu.ShowAsync(ContextMenuPosition.Top)" />

<div class="context-menu-container"
     @oncontextmenu:preventDefault>
    <span style="font-weight: 600">RIGHT-CLICK TO SHOW THE CONTEXT MENU</span>
</div>

<DxContextMenu @ref="ContextMenu"
               PositionTarget=".context-menu-container">
    <Items>
        <DxContextMenuItem Text="Open" />
        <DxContextMenuItem Text="Copy" />
        <DxContextMenuItem Text="Delete" />
    </Items>
</DxContextMenu>
