<h3>Example Scenario: Accessing parent data.</h3>

<!---------------------- First Example ---------------------->

<div class="subhead">Stepping up through the views (tree of nested rendered templates)</div>

<pre>
var model = {
    specialMessage: function(...) { ... },
    theater: "Rialto",
    movies: [ ... ]
}

{{for movies}}
    &lt;tr>
        &lt;td>'{{>title}}': showing at the '{{>#parent.parent.data.theater}}'&lt;/td>
</pre>

<table>
        <thead><tr><th>Title</th><th>Languages (+specialMessage)</th></tr></thead>
        <tbody id="movieList1"></tbody>
</table>

<!---------------------- Second Example ---------------------->

<div class="subhead">Setting contextual template parameters, accessible in all nested contexts as <em>~nameOfParameter</em>:</div>

<pre>
{{for movies ~theater=theater}}
    &lt;tr>
        &lt;td>'{{>title}}': showing at the '{{>~theater}}'&lt;/td>
</pre>

<table>
        <thead><tr><th>Title</th><th>Languages (+specialMessage)</th></tr></thead>
        <tbody id="movieList2"></tbody>
</table>

<!---------------------- Third Example ---------------------->

<div class="subhead">Using the top-level data, accessible in all nested contexts as <em>~root</em>:</div>

<pre>
{{for movies}}
    &lt;tr>
        &lt;td>'{{>title}}': showing at the '{{>~root.theater}}'&lt;/td>
</pre>

<table>
        <thead><tr><th>Title</th><th>Languages (+specialMessage)</th></tr></thead>
        <tbody id="movieList3"></tbody>
</table>
