A combo box is a commonly used graphical user interface widget (or control). Traditionally, it is a combination of a drop-down list or list box and a single-line editable textbox, allowing the user to either type a value directly or select a value from the list. The term "combo box" is sometimes used to mean "drop-down list".{{cite web |url=https://jkorpela.fi/forms/combo.html |title=Combo boxes in forms on Web pages |access-date=18 November 2008 |work=IT and communication |date=February 15, 2007 |archive-url=https://web.archive.org/web/20170815000301/http://www.cs.tut.fi/~jkorpela/forms/combo.html |archive-date=15 August 2017 |url-status=live }} In both Java and .NET, "combo box" is not a synonym for "drop-down list".{{cite web |url=http://docs.oracle.com/javase/tutorial/uiswing/components/combobox.html |title=How to Use Combo Boxes (The Java™ Tutorials > Creating a GUI With JFC/Swing > Using Swing Components) |publisher=Docs.oracle.com |date=2012-02-28 |access-date=2014-06-30 |archive-url=https://web.archive.org/web/20140811025542/http://docs.oracle.com/javase/tutorial/uiswing/components/combobox.html |archive-date=2014-08-11 |url-status=dead }}{{cite web |url=http://msdn.microsoft.com/en-us/library/system.windows.controls.combobox.aspx |title=ComboBox Class (System.Windows.Controls) |publisher=Msdn.microsoft.com |date=2014-06-20 |access-date=2014-06-30 |archive-url=https://web.archive.org/web/20140216095005/http://msdn.microsoft.com/en-us/library/System.Windows.Controls.ComboBox.aspx |archive-date=2014-02-16 |url-status=dead }} Definition of "drop down list" is sometimes clarified with terms such as "non-editable combo box" (or something similar) to distinguish it from "combo box".
