I am currently working on this ¿Cómo usar Gmail para leer correo de otras cuentas a través de POP3?
(my first document published in CODA) and was wondering how can I remove left navigation bar
that can be seen in the attached picture.
Hey Alejandro! The left-side navigation panel cannot be removed, but you can “hide” it by clicking on the double-arrow icon to the right of the search bar.
That being said, we’re happy to track this as a feature request for you in the meantime! Just let us know 
Hi Alejandro,
What you can also do is to publish the doc with navigation at the top. That will remove the sidebar.
