+## Description
+
+I want to visually separate the items in a [DropDownButton](slug:dropdownbutton-overview) to enhance the UI and improve user experience. How to add a separator (divider) between the items?
+
+## Solution
+
+The DropDownButton does not have a concept for a "separator" item (similar to the [ContextMenu](slug:contextmenu-data-binding-overview), for example). However, the DropDownButton uses a declarative approach for its items, so you can add any desired item.
+
+The specific is that the content you declare in the DropDownButtonItem will be rendered inside the `<span class="k-menu-link-text">` which is narrower and thus your custom separator will not cover the whole width of the popup. This article demonstrates how to add a separator by utilizing custom styling.
+
+To create a visual separator between items in a DropDownButton, apply a custom class to the item that precedes the separator and style its bottom border. This approach allows you to simulate a separator without the need for a dedicated separator item. The custom class can be applied directly in the item declarations in your Blazor component.

+    {
+        Console.WriteLine($"User clicked {item} option.");
+    }
