title: Accessing values of a map inside handlebar template file
body: <p>In the handlebar template file 
  where content is elements of the map:</p>
  
  <pre><code>map {&lt;"1" -&gt; [{:a =&gt; "1",:b =&gt; "as"},{:a =&gt; "2", :b =&gt; "hj"}]&gt;,&lt;"4" -&gt; [{:a =&gt; "we",:b =&gt; "kj"}]&gt;,......}
  </code></pre>
  
  <p>I want to know how to iterate over the elements of all structures of each list for each key of the map inside handlebar file</p>
  
  <p><strong>EDIT</strong></p>
  
  <pre><code>{{# each content}}
    key: {{@key}} value = {{this}}
    ....
  {{/each}}
  </code></pre>
  
  <p>value is list of structures.
  I want to iterate over the items in each structure in the list how to do that</p>
