A drop down field allows the user to choose one value from a list of predefined values. The list is hidden by default and displays only after the user clicks the arrow in the field.
When you configure a drop down, add a value to the list by typing the value in the Options field and then clicking the Add icon. Remove a value from the list by selecting the value and clicking the Delete icon. You can also arrange the positions of each value in the list by selecting a value and clicking either the Up or Down arrow.
In addition, you can specify a dependency on one or more prior fields on the form. A dependency on a prior field controls whether or not the drop down appears on the form and can be based on any value entered in the field or on a precise value.
