Open another field according to a certain choice

[Ángela Alcoba]

Good afternoon, I need to know how to condition a drop-down field according to what was chosen in the previous one. For example, if in a drop-down field I have to choose "Countries", according to the country chosen, in the next field to show me the "States" that make up that Country.
Thank you very much!

Try adding a "cascading select list" custom field.

Good morning Nic, what I need is to condition the options of that drop-down field according to what was chosen previously. Automatically if I choose an option, in the following field show me a dropdown of options referring to what I chose earlier. Condition the options as previously chosen.

Regards!

This is what a "cascading select list" does.
