header_actions

The header_actions hook is used to specify any additional action links in the page chrome header. The content provided will be rendered as an <li> inside the <ul> element that contains the Login/Logout and Proxying links.

This is not a Standard (3-Option) Hook, and should therefore not be called using content_for.

Usage

• View level: use the set_headers_actions, as in the first example below:

  // app/views/resources/show.html.erb
  
  <% set_header_actions(
    link_to('Email PO', gather_feedback_path, class: 'btn btn-link')
  ) %>
  

  (NB: the 'btn btn-link' classes, which will help it look like its fellow header actions)

• Helper/controller:

  # app/controllers/application_controller.rb
  
  class ApplicationController < PmacsAppResources::BaseController
    def header_actions
      [helpers.link_to('File Report',
                       'https://hamsterdance.gov',
                       class: 'btn btn-link')]
    end
    helper_method :header_actions
  end
  

Dropdowns

You can also render dropdown links by passing an array item that is a hash with some required keywords.

[
  {
    text: 'Dropdown',
    preface: helpers.tag.div('This is an optional preamble', class: 'text-grey-darker m-4'),
    children: [
      { text: 'This one is a link', props: { href: '#' } },
      'This one is plain text'
    ]
  }
]

Arbitrary content

You can pass in arbitrary content to be rendered within a li.nav-item element by supplying a hash entry with the content: keyword:

[
  { content: 'Just a string' },
  { content: '<div class="text-red-700>Custom HTML, too</div>'.html_safe },
  { content: render_to_string(partial: 'shared/global_search') },
  { content: helpers.tag.marquee('Remember <marquee> elements?!') }
]

Remember that your content must be marked as HTML-safe or else it will be sanitized. You can do so with .html_safe, or by using render_to_string(partial: 'my_cool_partial') or helpers.tag.<tag here>, both of which mark their output as HTML-safe.
