 CMS Kit is a set of reusable *Content Management System* features packaged as an ABP application module. We had published the first usable version with the previous release. With this release, we are adding another feature to the CMS Kit module: You can now dynamically arrange the main menu on the UI, which is an essential feature for any kind of content management system. In this way, you can add pages or any kind of arbitrary URLs to the main menu from the UI.

+Two new extension methods are added to `ObjectExtensionManager.Instance` to override EF Core mappings of [pre-built application modules](https://docs.abp.io/en/abp/latest/Modules/Index).
+
+**Example: Change mappings for the `IdentityDbContext` to override mappings for the `IdentityUser` entity**
+
+````csharp
+ObjectExtensionManager.Instance.MapEfCoreDbContext<IdentityDbContext>(modelBuilder =>
+{
+    modelBuilder.Entity<IdentityUser>(b =>
+    {
+        b.ToTable("MyUsers");
+        b.Property(x => x.Email).HasMaxLength(300);
+    });
+});
+````
+
+The startup template contains a class, like `YourProjectNameEfCoreEntityExtensionMappings`, that can be used to place that code.
