The :content_for plugin is designed to be used with the :render plugin, allowing you to store content inside one template, and retrieve that content inside a separate template.
Most commonly, this is so view templates can set content for the layout template to display outside of the normal content pane.
The content_for template probably only works with erb templates, and requires that you don't
override the :outvar render option.
In the template in which you want to store content, call #.content_for with a block:
<% content_for :foo do %>
Some content here.
<% end %>In the template in which you want to retrieve content, call #.content_for without the block:
<%= content_for :foo %>#.content_for(key, &block)If called with a block, store content enclosed by block under the given key.
If called without a block, retrieve stored content with the given key, or return nil if there is no content stored with that key.
