This is useful for inheritance of common shortcode arguments from the root.
In this contrived example, the "greeting" shortcode is the parent, and the "now" shortcode is child.
{{< code file=content/welcome.md lang=md >}}
{{</* greeting dateFormat="Jan 2, 2006" */>}}
Welcome. Today is {{</* now */>}}.
{{</* /greeting */>}}
{{< /code >}}
{{< code file=layouts/shortcodes/greeting.html >}}
<div class="greeting">
{{ trim .Inner "\r\n" | .Page.RenderString }}
</div>
{{< /code >}}
{{< code file=layouts/shortcodes/now.html >}}
{{- $dateFormat := "January 2, 2006 15:04:05" }}
{{- with .Params }}
{{- with .dateFormat }}
{{- $dateFormat = . }}
{{- end }}
{{- else }}
{{- with .Parent.Params }}
{{- with .dateFormat }}
{{- $dateFormat = . }}
{{- end }}
{{- end }}
{{- end }}
{{- now | time.Format $dateFormat -}}
{{< /code >}}
The "now" shortcode formats the current time using:
1. The `dateFormat` argument passed to the "now" shortcode, if present
2. The `dateFormat` argument passed to the "greeting" shortcode, if present
3. The default layout string defined at the top of the shortcode
