# HasMany Form Partial

This partial renders an input element for has_many relationships.
By default, the input is a collection select box
that displays all possible records to associate with.
The collection select box supports multiple inputs,
and is augmented with [Selectize].

## Local variables:

- `f`:
  A Rails form generator, used to help create the appropriate input fields.
- `field`:
  An instance of [Administrate::Field::HasMany][1].
  Contains helper methods for displaying a collection select box.
