# Ring Controls Overview

Use ring controls to select from a group of items. Each item is stored in the ring control in the form of a label/value pair, where the label is the text string displayed by the control when the item is selected, and the value is the numeric—or string—value corresponding to that item. A sample ring control appears in the following figure.
