yCode JavaScript ComboBox is a Java applet which allows you to add a combo box, where you can enter a value directly or select one from a drop-down list, to any HTML document.

In addition to the basic combo box properties, you can control several others. The entries in the drop-down list can be sorted; a default selection can be set; values that already exist in the drop-down list can be automatically looked up as the user enters in the data; and values can be added to or deleted from the combo box.
