title: What html5 tag should be used for filtering search results
body: <p>If I have an area of a page with different options for filtering the search results (unordered lists with links, checkboxes, selects, etc.). What html5 tag should be used to wrap that filters? A "section" tag, a "nav" tag or something else?</p>
  
  <pre><code>&lt;div id="search-filters"&gt; &lt;!-- This should be a div, a nav, a section? --&gt;
      &lt;h3&gt;Price&lt;/h3&gt;
      &lt;ul&gt;
          &lt;li&gt;less than 100&lt;/li&gt;
          &lt;li&gt;100 - 200&lt;/li&gt;
          &lt;li&gt;more than 200&lt;/li&gt;
      &lt;/ul&gt;
  
      &lt;h3&gt;Brand&lt;/h3&gt;
      &lt;ul&gt;
          &lt;li&gt;Brand A&lt;/li&gt;
          &lt;li&gt;Brand B&lt;/li&gt;
          &lt;li&gt;Brand C&lt;/li&gt;
      &lt;/ul&gt;
  
      ...
  &lt;/div&gt;
  &lt;section id="search_results"&gt;
      ...
  &lt;/section&gt;
  </code></pre>
