I am looking to add a way for users to input varables into WP menus:
"onclick="_gaq.push(['_trackEvent', 'Nav Name', 'Nav Click', 'Nav Item']);"
The requirment is the customer would like to have field in the advanced menu proprties where the user can input 'Nav Click', 'Nav Item'.
I am having a hard time finding documentation on how to add custom fields the wp menu console screen. Does anyone have any suggestions.
