Notice: As of 02/2018, pages with less than 2,000 likes cannot install HTML Fangate/Static tabs. Those pages will still be able to install all other campaign tabs or social media tabs.
The easiest way to add and manage all the Woobox tabs on your Page is through your Dashboard (log in now to access your account). This can be done with a free account, just sign up here if you haven't done so already and get started right away!
Once you've logged into your account, you'll just want to go to the Static Tabs section via the main navigation bar, and then click the Create a New Tab button in the upper right corner of the screen, and select the type of static tab you'd like to add from the list of options.
