If you don’t have a responsive theme, the WP Responsive Menu plugin might be a good way to adapt your site’s navigation into something that’s more presentable for mobile devices. It’s designed to take your standard WordPress menu and turn it into a sliding menu that’s optimized for mobile.
It integrates well and is easy to use. You can select custom colors to make sure the menu matches your current theme. You can remove certain items from the mobile view for easier viewing. You can even add your company’s logo to the menu to keep things consistent. There aren’t any bells and whistles here but this plugin picks a function and does it well.
