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 a brand new WPBakery Page Builder addon with new content elements and sell it on CodeCanyon (extra cash never hurts, right?).
