# Create control list selectors

Use the control list selector to select from a list of states for a process or operation. The list is highlighted to show the current state, and the operator can scroll through the list to select a different state. The value assigned to the selected state is written to the data source.

When the control list object is selected, the operator can scroll through the list and select states using key buttons or by using the arrow keys and Enter key on a keypad or an external keyboard. Key buttons can also be linked directly to the control list selector so that they will work whether the selector is selected or not.

## To create a control list selector

1. In the Graphics Display editor, select Objects > Advanced > Control List Selector.
2. Drag the mouse to position and draw a rectangle the general size and location you want the selector to be.
3. Double-click the selector to open its Properties dialog box.
4. In the Properties dialog box, specify the how the selector looks, its states and tags and whether to use Enter key handshaking.
