Relation field type for selecting related records in forms.

Follows the same pattern as MishkaGervaz.Table.Types.Filter.Relation.

Modes

• :static - Load all options at once (default, for small datasets)
• :load_more - Paginated with "Load more" button
• :search - Searchable single select
• :search_multi - Searchable multi select

Examples

field :site_id, :relation do
  mode :static
  display_field :name
end

field :category_id, :relation do
  mode :search_multi
  search_field :name
  min_chars 1
end
