Chronoforms v7 external dropdown list - joomla

Hi I would like to ask if it was possible to create an external list in the dropdown form configurations.

I would like to have a list of cities that the user just has to select.
Inserting one at a time is possible but it is a lot of lines.

use a textarea and let the user add them 1 city per line.

or how do you want the user to insert the list ?

I would like to avoid typing errors, I would like the cities to be already listed.

So what is the problem with creating a dropdown with the full list of cities ? you can enter all the options or use the dropdown MultiLine setting to enter the cities in multiline format
