Guidelines for Creating a Check Box
If you create a check box control or check box list column, then use the following guidelines:
Make sure a check box is the appropriate way to display the data. If the data does not map to a yes or no reply, or if the meaning of the unchecked value is not obvious, then it is recommended that you use a list of values instead. For example, instead of using a check box labeled Standard, use a combo box labeled Shipping Method with a list of values that contain Standard and Next Day. For more information, see Creating a List of Values.
Avoid using a negative. For example, instead of Not Required, use Optional.
In a form applet, align the first characters in the labels and position them to before the check box.
