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 into the control or choose from a list of existing options. Today, the original distinction between a combo box and a drop-down list has often disappeared.
Combo boxes are typically applied to provide autocomplete or autotype functionality in a convenient way to the user.

“[Let] the Union of the States be cherished and perpetuated. Let the open enemy to it be regarded as a Pandora with her box opened; and the disguised one, as the Serpent creeping with his deadly wiles into paradise.”
