How do I save all of the Options that I have dynamically added to a Dropdown?

Hello!

I have created an input field and buttons that dynamically add/remove Options to a Dropdown menu while the program is running. How can I save all of the Dropdown Options when I close the program, so that I can load the Options on next start up? To clarify, I don’t need to save the Dropdown Option that is selected, I need to save all of the available Options.

Thank you for your help!

Dropdown from top menu ?

Dropdown from inspector ? (if they apears, they are already serialized

???
