Params	Returns a map of custom parameters as defined in the front matter of the given page.			functions_and_methods returnType signatures maps.Params PAGE.Params

By way of example, consider this front matter:

{{< code-toggle file=content/annual-conference.md fm=true >}} title = 'Annual conference' date = 2023-10-17T15:11:37-07:00 [params] display_related = true key-with-hyphens = 'must use index function' [params.author] email = 'jsmith@example.org' name = 'John Smith' {{< /code-toggle >}}

The title and date fields are standard front matter fields, while the other fields are user-defined.

Access the custom fields by chaining the identifiers when needed:

{{ .Params.display_related }} → true
{{ .Params.author.email }} → jsmith@example.org
{{ .Params.author.name }} → John Smith

In the template example above, each of the keys is a valid identifier. For example, none of the keys contains a hyphen. To access a key that is not a valid identifier, use the index function:

{{ index .Params "key-with-hyphens" }} → must use index function
