# List of Values (LOVs)

Alpha Numeric Data Type is also used in conjunction with a List of Values. Lists of Values are sets of data that are pre-configured to be the only possible answers in a given field. These can be configured in a few ways:

* Single Select: Allows the user to to select one value from a pre-determined list.
  * set '"allowMultiple" to false
* Multi-select: Allows the user to select multiple values from pre-determined list.
  * set "allowMultiple" to true
* Multi-Select Hierarchal: Allows the user to select multiple values from pre-determined list of values that have been structured in a hierarchal order.

| Value Precision | is AllowMultiple respected? | Has validation? |
| --------------- | --------------------------- | --------------- |
| -               | Yes                         | Only on length  |
