**Use case #12: Easily customizing page parameters**

My initial reflex while trying to set dynamic / nav parameters of the page (like a title, breadcrumbs..) was to use layout-level exposures in the views: `expose :title, :layout => true`

While technically possible, I found it a bit tedious to do, because in fact it made more sense to live inside the template itself, which receives all the useful information ready to use.

**This is possible very easily thanks to the context method `content_for`**  
[Views / Context · Hanami v2.3 · Hanakai](https://hanakai.org/learn/hanami/v2.3/views/context#standard-context)

That way, you can set a dynamic information from any template:

```html
<!-- templates/catalog/configuration.html.erb -->
<% content_for :title, "Configure catalog #{catalog.name}" %>

<div>
   <h1>Catalog configuration / <%= catalog.name %></h1>
</div>

```

And then use it from the layout, or any other template:

```html
<!-- templates/layout/app.html.erb -->
<html>
  <head>
    <title><%= content_for :title %></title>
  </head>
  <body>
    <%= yield %>
  </body>
</html>

```

In my example, this will render:

```html
<html>
  <head>
    <title>Configure catalog Foo</title>
  </head>
  <body>
    <div>
      <h1>Catalog configuration / Foo</h1>
    </div>
  </body>
</html>

```

Very simple, very powerful. I wished I’d knew it earlier 😅  
Happy coding ! 🌸🌞
