Please update the corresponding html file's comment about more than one sidebar: https://github.com/ampproject/amphtml/blob/master/extensions/amp-sidebar/0.1/test/validator-amp-sidebar.html#L49

I remember seeing a discussion about allowing only one left sidebar and one right sidebar, but not two left sidebars or two right sidebars. Is that no longer the case?

The reason we did not allow this was we did not want to open 2 sidebars and give no means of closing them (unless the author adds a close button on the sidebar).

We would also need this feature?
#3320

@camelburrito see comments on #6104 as I have mentioned I like to do this part without waiting for #3320

@honeybadgerdontcare maybe although considering with amp-bind now devs can have complicated logic, I can see use-case of having multiple sidebars on the same-side and using bind to open the one that makes sense given the state of the app.

@aghassemi yeah that makes sense, thanks for clarifying. It would be useful to have this if it was exercised in the right fashion.

@aghassemi i am okay with this as long as you promise #3320 will make it in soon :)

@camelburrito I am not yet fully convinced we need #3320, let's discuss on that issue.
