Visual Composer is extendable.
When a plugin becomes popular enough, you’ll often see third-party developers building their own plugins to extend the core plugin’s functionality. With 500,000 users, Visual Composer sits comfortably in this category, and a wide variety of add-ons have been developed for it — these add-ons are installed in the same way a plugin is.
Essentially, these add-ons allow you to extend the list of elements you can use with Visual Composer. Because most of the add-ons are premium, some of the functionality you can add to Visual Composer is pretty sophisticated.
If you’re a fan of what Visual Editor does, but the out-the-box version lacks the functionality your website needs, then one of the many Visual Composer add-ons could meet your requirements.
