# custom_objects.field_create

Criar campo em um objeto. Cria um campo no objeto. `fieldName` (a-z, 0-9, _) sai do rótulo se omitido e é único no objeto (repetido informado dá `invalid_input`; o gerado ganha `_2`, `_3`). `groupName` põe o campo num grupo e `unique: true` proíbe valor repetido entre registros. O tipo não muda depois. Os tipos `select`, `multi_select` e `radio` exigem `options` (lista de textos ou `{label, value}`); os demais não aceitam. Vai para o fim da lista.
