Hey! Thank you so much for publishing this code, it really helped me a lot.

Here is my slightly twisted version:

{{ .Scratch.Set "lastp" (sub (.Params | len) 1) }}
<details {{ if .Get 0 | eq "open"}} open {{ end }}>
    <summary>
        {{ i18n "click_to_open" }}{{ .Get (.Scratch.Get "lastp") | markdownify }}
    </summary>
    {{ .Inner | markdownify }}
</details>

Thanks for your sharing your code! Here is my version using named parameters:

{{ $open := .Get "open" | default "false" }}

<details
    {{ if eq $open "true"}}
        open
    {{ end }}
>
    <summary>
        {{ i18n "click_to_open" | default "Click to Open" }}
        {{ with .Get "title" }}
            {{ . | markdownify }}
        {{ end }}
    </summary>
    {{ .Inner | markdownify }}
</details>

That's great!
Thanks!!
