I created a plugin settings page following the example shown here but my entries need to include multilines (they are email bodies). My Twig template for the settings page is like this:

{% import "_includes/forms" as forms %}

{{ forms.textField({
    label: "Submitted Subject"|t,
    id: 'submittedSubject',
    name: 'submittedSubject',
    instructions: "Input your setting"|t,
    value: settings.submittedSubject,
    errors: settings.getErrors('submittedSubject'),
    })
}}

(this field is repeated 6 times). I tried using textAreas instead of textFields, but it doesn't have the same options and I don't think it works (doesn't have a value field). Also it doesn't help that there's barely any documentation for this. Is there a way for me to have multiline text inside the text field?
