Tab/Accordion/Toggle WPBakery Content Is Messed Up
Tabs (as well as accordion and toggles) are not supposed to be used within complicated combination. We can only assure correct functioning of simple content inside of a tab (text, images, standard WP gallery, lists):
Content of hidden tabs is not being displayed. In result, a script cannot calculate height and width of inner elements and cannot place them correctly inside of a tab.
You can try to insert this script LINK in “RAW JS” Visual Composer element directly into page content . But please consider that this solution may slowdown your web-site and work only with limited number of shortcodes.
