SQL Filter in component

Hi team,

English:
What is the possibility of creating a field in the registration form of the component causing it to pull information from the sql based on information from a field above? for example: I have a State field and the other city, both have information in the database, by selecting the State field below pulls only the cities with references in that State or province

Brazilian Portuguese
Qual a possibilidade de criar um campo no formulário de cadastro do componente fazendo com que ele puxe informações do sql com base em informação de um campo acima? por exemplo: tenho um campo Estado e o outro cidade, ambos possuem informações no banco de dados, ao selecionar o estado o campo abaixo puxa apenas as cidades com referencia naquele esta

Hi,

How did you set up the State and City lists? I think you could set up the City field as a foreign key, and use the State as the key, then you can automatically filter the City value by State.

that's exactly what I do Mekalb, on city table has a column named state_id which is the reference of another State table, when I say I mean State (region with numerous cities, like a province)
But the great doubt is when you do it all the time here in the component creator

Thanks
