How to structure

# A collapsible section with markdown
<details>
  <summary>Click to expand!</summary>
  
  ## Heading
  1. A numbered
  2. list
     * With some
     * Sub bullets
</details>

Two important rules:

  1. Make sure you have an empty line after the closing </summary> tag, otherwise the markdown/code blocks won't show correctly.
  2. Make sure you have an empty line after the closing </details> tag if you have multiple collapsible sections.
