I have, for example, two tables: 1. cars with fields id, car_name 2. models with fields id, car_id, model_name

I want to use two combo-boxes to gather inputs. In first combo-box I want to have cars name and into the second I want to have model names filtered by car_id.

It's possible to do it?

Thank you Sergey, for your's quick reply. I saw the video but, unfortunately, it present the possibility to put in relation two (or more) articles. I wander if it is possibly to put in relation two fields which belong to the same article. May be, could I referer to the value that was selected into a select field type? Something like this (sql sources for the second select field type - models): select 'id' as id, 'model_name' as text from 'models' where 'models.car_id' = cars_field.value where cars_field.value is the value that was selected into the first select field type

You need to use Multiple Level Select Field.

This fields allows create tree like structures. You chose first level, then second level appear.

Thank you very much. Exactly what I need. Now, I have another challenge. How can I generate the import file using my tables?

Import is limited in Cobalt. Not all fields support import and only specific formats of text suported like select calues as strings separated by coma.
