Several graphical objects are suitable to display using a limited set of possible values the user must choose from.

A combo box is a list of values that displays the current field value and drops down into view when the user clicks an arrow icon to the right of the current value. This makes it effectively a combination of a list box and a text box. The user can then select a different value from the list or, depending on how the combo box has been set up, enter a value not already on the list. A combo box is, therefore, an appropriate visualization when you do not want the list of choices displayed at all times and also when it is sometimes valid for the user to enter a value not on the choice list.

A selection list displays a list of values the user can choose from. Though the list is not contracted after the user chooses a value, you can provide a scrollbar to allow more possible values than can reasonably be displayed at one time. You can define a selection list to allow multiple selections, making it an appropriate visualization when the user must be able to pick more than one value or when the number of possible values is long enough that it requires a scrolling list.

If you need to provide a choice from a large or potentially large number of values, a browse can be an appropriate object to use as a selection list without real limits on its size.

To display a small number of choices in either a vertical or horizontal format, you can also use a radio set object.
