Parent

Returns the parent shortcode context in nested shortcodes.

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.

{{< greeting dateFormat="Jan 2, 2006" >}}

{{- $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 -}}

The “now” shortcode formats the current time using:

The dateFormat argument passed to the “now” shortcode, if present
The dateFormat argument passed to the “greeting” shortcode, if present
The default layout string defined at the top of the shortcode
