title: Meteor Dropdown list get and set
body: <p>What is the best way to get and select values from a dropdown list (and also in radio) in Meteor. 
  I have created a helper: </p>
  
  <pre><code>Template.categories.helpers({
      categories: ["facebook", "news", "tv", "tweets"]
  });
  </code></pre>
  
  <p>and in html </p>
  
  <pre><code>...
  &lt;select class="form-control" id="category"&gt;
    {{&gt; categories}}
  &lt;/select&gt;
  ...
  &lt;template name="categories"&gt;
    &lt;option disabled="disabled" selected="selected"&gt;Please Select&lt;/option&gt; 
      {{#each categories}}
        &lt;option value="{{this}}"&gt;{{this}}&lt;/option&gt;
      {{/each}}
  &lt;/template&gt;
  </code></pre>
  
  <p>In case of edit, I would like to evaluate it with value coming from database (e.g. news) to be selected.</p>
  
  <p>Thanks in advance.</p>
