Palette Fields
PaletteField objects display a list of values, represented as images, from which the user selects a single value. Like radio fields, all choices are always displayed in a palette field. Therefore, the list should contain few choices.
Each value in a palette field has text, an associated numeric value, and an image. PaletteField objects are mapped to variables of either varchar or integer data type. However, regardless of the variable mapping, the palette field always displays the list of choices as images.
