A combo (combination) box is a text box containing a small “drop down” button. When that button is pressed, a scrollable list of choices for the text field is displayed. The combo box can be defined to allow only those alternatives shown in the list to entered, or to be fully editable like a text box. Using the “Edit/Properties” option you can set the following attributes:
Label – The text on the left hand side of the box identifying it to the user.
Width – The width in font units of the text box plus the drop down button.
Height – The number of visible items in the drop down list.
Editable – Defines whether or not you can edit the text field, or if its restricted to contain only one of the items shown in the drop down list.
Sorted alphabetically – If checked, items in the drop down list will be shown in alphabetical order.
