# `MishkaGervaz.Form.Types.Field.Combobox`
[🔗](https://github.com/mishka-group/mishka_gervaz/blob/v0.0.1-alpha.3/lib/mishka_gervaz/form/types/field/combobox.ex#L1)

Combobox field type: text input with dropdown suggestions.

Combines free text entry with pre-loaded option suggestions.
Users can type any value or select from the suggestion list.

Options are resolved once at form initialization (not on every render),
making it efficient for database-backed suggestion lists.

## Example

    field :language, :combobox do
      options fn ->
        case Ecto.Adapters.SQL.query(Repo, "SELECT DISTINCT language FROM posts") do
          {:ok, %{rows: rows}} -> Enum.map(rows, fn [lang] -> {String.upcase(lang), lang} end)
          _ -> []
        end
      end
    end
