How set conditional dropdown CF7

Overview

The issue is needing to show different fixed-list options in a second dropdown based on the selection in a first dropdown.
Use a PHP action to return an array of options based on the first dropdown's value, then reference that PHP action's variable in the second dropdown's dynamic options setting.

So your options are a fixed list, not from a Database table ?

Hi Roman,

it works like the database, but instead of using a "Read Data" action, you will need to use either 1 PHP action or multiple "Variables" actions, the PHP should check the value passed from the first dropdown and return an array of values, then use {var:php_name} as the data source of the "Dynamic options" setting in the 2nd dropdown!

here is an example return value to be used as the data source

return [
["text" => "option 1", "value" => "op1"],["text" => "option 2", "value" => "op2"]
];

the PHP action will not be selectable in the source list in the dropdown settings, just type it instead of selecting:

{var:php_4}
