Hi,
when samples contain experimental component, it's normal that they don't validate.
amp-form is experimental, so all the examples containing it will fail the validation, such us amp-form and housing.

amp-fix-flying-carpet is experimental, see doc
amp-live-list is experimental, see doc

amp-side-bar should work, but probably the problem is that we are using that twice in the page (for the left menu and the example itself). Please create an issue just for this.

Hope it helps.

The amp-sidebar sample is tricky to get to validate. There are two problems:

1. amp-sidebar needs to be the first element after the body tag (see Make amp-sidebar sample validate #167)
2. only one sidebar is allowed per page and we have two together with the ABE navigation menu.

Would it be possible to use an amp-iframe for the script tag (experimental mode)?
This would also allow to have the amp-sidebar as a child of for example in this page: https://ampbyexample.com/samples_templates/product/preview/

We can't use an iframe for triggering experimental mode -> experimental flag is stored via cookie which needs to be set for the document host.

Fixing samples with amp-sidebar needs to be handled during the example compilation step.
