I am created a contact form in Wordpress, using Contact form 7 - plugin.
Is it possible to create a dropdown-menu, in which, an action is triggered when the user selects one of the options from the menu? e.g. displays an alert saying something like "great choice"?
Here so we select your dropdown menu, we then create a event handler to watch for the user to click on there and then we simply use alert
$('.YourDropDownClass').click( function(){
alert('Great Choice!');
});
