You can add shortcodes in both Visual Composer and Massive Builder. But if you add a tab shortcode to a page using Visual Composer back-end editor, you can't add content to that tab shortcode. For adding content to tab shortcodes, you need to use Massive Builder.
To do that, please open that page in Massive Builder and move your mouse over tab shortcode. You can select different tabs by clicking on them. Now drag and drop your desired shortcodes in content section.
