WPBakery Page Builder was designed and built to be easily extendable. Currently, we have 250+ WPBakery Page Builder add-ons that were designed to take your site to the next level. Right after addon activation, it will add extra functionality to your site.
Are you a developer? If so, then you should definitely check our knowledge base and make your plugin “WPBakery Page Builder ready” or create brand new WPBakery Page Builder addon with new content elements and sell it on CodeCanyon (extra cash never hurts, right?).
