R Markdown Presentation: How to continue a numbered list across a slide?

Question

Let's say I want to create this numbered list:

1. Sed ut perspiciatis unde omnis iste natus error...
2. Nemo enim ipsam voluptatem quia voluptas sit...
3. Neque porro quisquam est, qui dolorem ipsum quia...
4. Quis autem vel eum iure reprehenderit qui in ea voluptate...

In R Markdown, the documentation suggests that to continue such a list after an interruption, one should prepend each list item with (@) as follows:

(@) Sed ut perspiciatis unde omnis iste natus error...
(@) Nemo enim ipsam voluptatem quia voluptas sit...

 This is an interrupting block of text...

(@) Neque porro quisquam est, qui dolorem ipsum quia..
(@) Quis autem vel eum iure reprehenderit qui in ea voluptate...

and this will continue the numbering after the interruption.

However, I tried, without success, to use this approach in continuing a numbered list in an ioslides presentation generated from R Markdown i.e.

(@) Nemo enim ipsam voluptatem quia voluptas sit...

 ***

(@) Neque porro quisquam est, qui dolorem ipsum quia..

where *** represents the slide break.

Is there a way I can achieve number continuation across the slide break?

Answer 1

You can use the HTML <ol> tag (ol is for ordered list) which has an optional start argument.

Here is minimal example:

---
title: "Untitled"
output: ioslides_presentation
---

## Slide

<ol>
<li> Sed ut perspiciatis unde omnis iste natus error...
<li> Nemo enim ipsam voluptatem quia voluptas sit...
</ol>

This is an interrupting block of text...

<ol start=3>
<li> Neque porro quisquam est, qui dolorem ipsum quia..
<li> Quis autem vel eum iure reprehenderit qui in ea voluptate...
</ol>

This also works across slides.
