# `MishkaGervaz.Form.Verifiers.ValidateGroups`
[🔗](https://github.com/mishka-group/mishka_gervaz/blob/v0.0.1-alpha.3/lib/mishka_gervaz/form/verifiers/validate_groups.ex#L1)

Validates the `groups` section of MishkaGervaz form DSL.

Two checks:

  1. Every group field reference exists in the form's declared fields.
  2. No field appears in more than one group (groups partition fields).

See `MishkaGervaz.Form.Dsl.Groups`,
`MishkaGervaz.Form.Entities.Group`,
`MishkaGervaz.Form.Verifiers.Helpers`, and sibling verifiers.
