  Hi misters,
  
  I use ASP.NET WebForms 2025v2 399, i’m migrating from 2012v1 to 2025v2 399.

  Now, not compiles this code using NestedGroupCheckable and ImageUrl

                  // NEW
  		//var nmit = new C1.Web.UI.Controls.C1Menu.C1MenuItem(gmi.Description);
  		var nmit = new C1.Web.Wijmo.Controls.C1Menu.C1MenuItem();
    nmit.Text = gmi.Description;
  
  		nmit.NestedGroupCheckable = false;
  
  		mi.ImageUrl = gmi.IconUrl;

  any suggestions ?

  Hello,

  Older API reference: https://helpcentral.componentone.com/nethelp/c1menu/default.htm

  NestedGroupCheckable:
  
  According to the original API definition, this property indicates whether child menu items are checkable.
  
  In 2025v2, menu items and their child items do not include checkboxes by default. If you need to add checkboxes to child items, this can be achieved using menu templates:
  
  https://developer.mescius.com/componentone/docs/webforms/online-menu/templates.html

  If your requirement is to implement selection behavior for menu items, you can handle this using client-side events:
  
  https://developer.mescius.com/componentone/docs/webforms/online-menu/clientsideevents.html

  ImageUrl:
  
  Per the original definition, this property was used to specify the image displayed next to the menu item text.
  
  In 2025v2, similar functionality can be implemented using menu templates:
  
  https://developer.mescius.com/componentone/docs/webforms/online-menu/templates.html

  or by using jQuery UI icons:
  
  https://developer.mescius.com/componentone/docs/webforms/online-menu/menuitemicons.html

  We have implemented these approaches in the attached sample for your reference (Menu_Sample.zip).
