The separator item is a horizontal or vertical bar used to provide visual separation between items/commands in a group, toolbar, StatusBar or drop-down menus.

The separator can be added at design-time using the Floating Toolbar or Collection Editor. Refer this topic for detailed information. A separator can also be added to the C1Ribbon control through the code using the RibbonSeparator class. This is depicted in the code snippet below:

' リボン項目の区切り記号を追加します
Dim separatorItem As RibbonSeparator = New RibbonSeparator()
formatGroup.Items.Add(separatorItem)

// リボン項目の区切り記号を追加します
RibbonSeparator separatorItem = new RibbonSeparator();
formatGroup.Items.Add(separatorItem);
