--- title: Params description: Returns a map of custom parameters as defined in the front matter of the given page. categories: [] keywords: [] params: functions_and_methods: returnType: maps.Params signatures: [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](g) the [identifiers](g) when needed: ```go-html-template {{ .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: ```go-html-template {{ index .Params "key-with-hyphens" }} → must use index function ``` [`index`]: /functions/collections/indexfunction/ [front matter fields]: /content-management/front-matter/#fields
