I looked (surfed) around a lot to get idea of how can I add custom field/drop-down under "Menu Settings" in WordPress Admin.
I want a
select tag with options from which I can get value based on the current selected menu.
Below image shows the basic idea what I am trying to get:
I want this to associate value for each selected menu and get it for dynamic theme style for the menu.
P.S. I am new to WordPress Development, please bear me.
Your help would be really appreciated.
