With CB Conditional, yes, you can chain fields together. Just be sure value resetting is enabled when chaining a set of 3 like that.

Hello, I am trying to create with CB Conditional of the Dropdown related that reading the values ​​from the database.
Example: I have 3 Dropdown and in the database:

Continent State City
Europe Italy Milan
Europe Italy Rome
Europe Germany Berlin
Europe Germany Monaco
Europe Spain Madrid
Europe Spain Barcelona

how is it possible to filter the dropdown directly on the database, so that if I choose Europe the second Dropdown to return

Italy
Germany
Spain

and if I choose Italy, the third Dropdown to retarn

Milan
Rome

Thank you.

You can't, it doesn't ajax update a query field or anything like that. You can only show/hide the field. You would need multiple fields and then show/hide them as needed or make them a normal single select field and show/hide their options using a conditional other.

I have a table with more than three hundred lines, then it becomes difficult to manage it yourself, hiding or showing certain values.
Is there one way using CB Query 3 with a sql statement (Eg: SELECT `city` FROM `table` WHERE `country` = `cb_nazione`) or by using a field of support (Eg: UPDATE `support-nation` SET `nation` = `cb_nazione`) and then use it as a filter for the city? Alternatively, is there some other kind of solution or plugin?
Thank you.

Pasquale

then use it as a filter for the city?

Yes, you can use substitutions in the query so you could have the following.

`country` = '[cb_nazione]'

However this won't do anything dynamically as they change the field. It would only do so when they refresh the page. There is no built in Ajax for what you're wanting.

Alternatively, is there some other kind of solution or plugin?

No.
