We want to use the amp-sidebar more than once in our website. The first sidebar (from left to right) will be used to display the navigation of our website. The second sidebar we want to for switching between our local sites, so the user can select another cinema and will get the actual playtimes of the movie. Technically it is possible to use two different sidebars with two different ids. But the AMP-Validator gives an error, because the amp-sidebar is only allowed once. Are you planning to allow more than one sidebar in an amp-website?

We have made an example of our desired implementation: http://download.cinemaxx.de/download/web/amptest/kinoauswahl.html
