The ChoiceType constants identify the choice list type for a field.
| Constant | Value | Description |
|---|---|---|
| _CLOSED_CHOICE | 1 | Must use a choice list option. This means that the valid values for the field are limited to those specified in a choice list. |
| _OPEN_CHOICE | 2 | Can enter something besides the choice list. The user may select an item from the choice list or type in a new value. |
