Hello,
Does anybody succeed in using markdown syntax into html’s “detail” tag 
  ?
In my case, markdown syntax is ignored.
        Example 1
       Using **bold** markdown syntax 
  
        Example 2
       Using `code` markdown syntax 
  
        Example 3
       ```
        blah
       ``` 
 
Thank u for your help,
Denis
             
            
              
              
              
            
                
            
           
          
            
            
              Markdown has no support for this, but you can use a shortcode.
Save this file as “detail-tag.html” to layouts/shortcodes:
    {{ $summary:= .Get 0 }} 
    {{ $content := Get 1 }}
    <details>
      <summary>{{summary}}</summary>
      <p>{{$content}}</p>
    </details>
Use in Markdown:
{< detail-tag "This is an example" "Examples are good for learning things and trying something new" >}
Or, you can just use the HTML tag and add | safeHTML to .content:
# Markdown with HTML
<details>
  <summary>Click to expand!</summary>
  
  ## Heading
  1. An entry
  2. list
     * With some
     * sub entries
</details>

{{ $summary:= .Get 0 }} 
{{ $content := .Get 1 }}
<details>
    <summary>{{$summary}}</summary>
    <p>{{$content}}</p>
</details>
