Feature request - allow slide=<index> to be set at page load time

[mikeatkinsonthesecond]

I've built an amp-carousel with a number of slides, each of which is relevant for a different time of day.

On pageload, I display an amp-list using some external JSON data. I would like to pass back in that JSON an indication of which slide should currently be displayed, and then call carousel.goToSlide to jump to that slide

This is currently not possible as carousel.goToSlide can only be triggered by a user interaction. This could apparently theoretically be supported by a selected attribute on a specific amp-carousel slide

/cc @choumx. I believe this is possible with <amp-bind>.

bind can change the slide via [slide] attribute but slide attribute is not available for the page load case.

@ericlindley-g and I were coincidentally talking about this yesterday. We should be able to support slide as a normal attribute and not just for bind.

I will take the issue.

Similar to #16110 #12659

I will take this for FIXIT.

Hi @aghassemi , willing to know is this FR been scheduled to implement? Having a partner blocked by setting default slide index differently when page is on-load.

@TWsky We are working on a new version of Carousel and CCed above is @nainar who is PMing the feature. Something we can consider for the new version. We could also consider adding this to the old one if @nainar sees fit.

Hi Everyone, I'm interested in this as well (to allow slide=<index> to be set at page load time). It looks like a really needed feature. I'll keep an eye on this thread for updates. 🙏
