    - Selection list
    - Bar trend
    - Combo box
      Combo boxes allow you to choose only one option from a list of pre-defined alternatives. Since only the selected option is displayed once the selection has been made, a combo box does not take up much space in a system diagram.
    - Check box
      Check boxes are lists containing small, square buttons to the left of the options, one or more of which can be selected ("checked") simultaneously. Check boxes differ in appearance from radio boxes that have a round shape.
