Support collapse for callout block in a revealjs presentation

[meersel]

The setting collapse="true" does not work in a revealjs presentation.

See code below:

:::{.callout-caution collapse="true"}
## Expand To Learn About Collapse

This is an example of a 'folded' caution callout that can be expanded by the user. You can use `collapse="true"` to collapse it by default or `collapse="false"` to make a collapsible callout that is expanded by default.

That's unfortunately a known limitation for the time being (we'll update the docs to reflect that)

[meersel]

Okay thank you for the feedback.

Will tachyons be supported in Quarto ?

Hope to meet you at the RStudio 2022 Conference. It is my first RStudio conference

[jjallaire]

Look forward to seeing you at the conference!

Not sure about tachyons being a built in feature but it's likely that a tachyons extension will emerge after we document how to write extensions.

Is there any progress on this issue? Thanks!

[mcanouil]

If the issue is still open with no additional comments, this likely means nothing new.

There is one extension on the subject for HTML format: https://github.com/shafayetShafee/collapse-callout

I've been using tachyons by including tachyons.min.css in my CSS specification, and adding the tachyons shortcuts as class specifications (separated by space) in div blocks

So

::: { .bg-light-blue .b--blue .tl .ba .bw2 .br3 .shadow-5 .ph4 .mt5 .f4 .avenir}

This works, but I'm sure there's a better solution out there

[sebacea]

A functional proposal should be something like this

::: panel-tabset
## Callout title

## Callout expansion

Content of expansion
:::

perhaps it serves for some inspiration to solve this issue

It's not a "functional proposal", it's a workaround as it completely discards the use of call-outs and uses panel tabset feature.

[sebacea]

Absolutely, call it whatever you like. It was only a proposal... trying to help
