Support for CTA Layer

[pietrop]

Hello,
We were looking to add a Call To Action to one of the cards, but can't seem to find it in the story-json spec. I am not sure how this will play with keeping compatibility between story-json and both /story-json-to-amp and story-json-to-video. But it be great if there was a way to add it?

see here for AMP docs on CTA

If there's a good way to do it, I'd be happy to do a PR if that helps.

Thanks

Yea, doesn't seem to be something we support at the moment.

I suppose story-json-to-video could just ignore that prop, since there's no way to do a cta really in a video.
@iefserge do you know if have we handled anything similar in story-json before?

@pietrop @ellell I think this can be handled by special option to story-json-to-amp, I'd imagine something like

{
  layersCTA: [
    {
      pageId: 'unique page id specified in story json',
      content: '<a href="http://www.google.com" class="button"> Call to action! </a>'
    }
  ]
}

I think due to AMP CTA layer size restrictions it would be hard to handle this nicely in a cross platform way, as we'll have to adopt the same restrictions.
