The ContextMenu is hidden behind the Modal Window

When I try to add a context menu to the content in the Modal Window the context menu stays behind the modal.


A possible workaround is to increase the z-index of the ContextMenu:

<TelerikContextMenu Data="@MenuItems" Selector="#menu-target"
                    Class="menu-on-top" />

    .k-animation-container:has(.menu-on-top) {
        z-index: 11000 !important;

<TelerikWindow Width="240px" Height="160px"
               Top="100px" Left="100px"
               Visible="true" Modal="true">
        <div style="height:60px;border: 1px solid;"
             id="menu-target">Right-click me</div>

@code {
    List<ContextMenuItem> MenuItems { get; set; } = new List<ContextMenuItem>();

    protected override void OnInitialized()
        for (int i = 1; i <= 7; i++)
            MenuItems.Add(new ContextMenuItem() { Text = $"Menu item {i}" });


    public class ContextMenuItem
        public string Text { get; set; } = string.Empty;

Hi Gregg,

The current item tracks the progress of the issue occurring with the UI for Blazor ContextMenu and Window components.

If you are experiencing a similar behavior using the UI for MVC product, you may open a dedicated report in the UI for MVC feedback portal.

We have the exact same problem but in the UI for MVC product (not fixed in the latest version). Have tried to set the z-index, but still have the same issue.

This is very helpful thank you! 
The secret sauce of this work-around is the z-index of 11000. The pop-up window has a z-index of 10003 in my case. Setting the z index to anything lower than the window puts it behind the window.
