        margin-top: 15px;
        height: 50px;
        width: 200px;
        border: 1px solid black;
    }
</style>

<DxButton Text="Show Context Menu" Click="() => ContextMenu.ShowAsync(0, 25, ContextMenuPosition.Right)" />

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

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

@code {
    DxContextMenu ContextMenu { get; set; }
}
