A list box is a graphical control element that allows the user to select one or more items from a list contained within a static, multiple line text box. The user clicks inside the box on an item to select it, sometimes in combination with the ⇧ Shift or Ctrl in order to make multiple selections. "Control-clicking" an item that has already been selected, unselects it.
A list box is called select or select1 in the XForms standard. Select is used for allowing the user to select many items from a list whereas select1 only allows the user to select a single item from a list.
