If your menus are not responsive yet, then the Responsive Menu plugin is a must for any self-respecting WordPress site owner. It’s a highly customizable plugin with free and paid versions.

The menus it creates are responsive as well as touch & retina ready.

It also allows quite a lot of effects in the menu, such as hover; hover intent or click event to open sub menus; fade, fade up, slide up or slide sub menu transitions; and add icons. In addition to all these cool features you can find in the free version, there are many more in the paid one.

3. All in Menu

All in Menu is another mega menu WordPress plugin you can use to create dynamic and responsive header mega menus. A drag and drop plugin, too, itt isn’t as popular as Max Mega Menu and doesn’t offer as many customization options, but this isn’t a reason not to try it. You can choose the alignment of the menu items, as well as their colors and width.

4. WP Mobile Menu

If your site enjoys a lot of mobile traffic, you are not quite satisfied with what responsive themes do for it, and you want something created specifically with mobile visitors in mind, try WP Mobile Menu. It’s a responsive plugin you can use to override your present theme’s menu options. It’s fully customizable in terms of appearance and functionality, and you can even add widgets to it.

5. If Menu

The types of conditions at your disposal are user state (e.g. logged in or not), user roles (admin, etc.), page types (homepage, etc.), and device types (e.g. mobile). For more advanced users, there is also the option to set your own conditions.

6. Menu Buttons

To avoid this, put some of the plugins in this article to use – this will certainly make the lives of you and your users much easier as far as site navigation is concerned.
