title: Horizontal Menu with Vertical Submenu (HTML/CSS Only)
body: <p>I'm having a difficult time trying to make my submenu vertical instead of horizontal. Any help would be much appreciated.</p>
  
  <p>HTML:</p>
  
  <pre><code>&lt;ul id="menu"&gt;
    &lt;li&gt;&lt;a href="/" title="HOME"&gt;HOME&lt;/a&gt;&lt;/li&gt;
    &lt;li&gt;
      &lt;a href="/" title="ECO ENERGY"&gt;ECO ENERGY&lt;/a&gt;
      &lt;ul&gt;
        &lt;li&gt;&lt;a href="/Evaluations" title="Evaluations"&gt;Evaluations&lt;/a&gt;&lt;/li&gt;
        &lt;li&gt;&lt;a href="/Incentives" title="Incentives"&gt;Incentives&lt;/a&gt;&lt;/li&gt;
        &lt;li&gt;&lt;a href="/HouseFiles" title="House Files"&gt;House Files&lt;/a&gt;&lt;/li&gt;
        &lt;li&gt;&lt;a href="/UpdateSubmissions" title="Update Submissions"&gt;Update Submissions&lt;/a&gt;/li&gt;
      &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt;
        &lt;a href="/" title="NEW HOMES"&gt;NEW HOMES&lt;/a&gt;
        &lt;ul&gt;
          &lt;li&gt;&lt;a href="/NH" title="Evaluations"&gt;Evaluations&lt;/a&gt;&lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
  &lt;/ul&gt;
  </code></pre>
  
  <p>CSS:</p>
  
  <pre class="lang-css prettyprint-override"><code>#menu {
    background-color: #206676;
    float: left;
    width: 100%;
    height: 60px;
  }
  
  ul#menu {
    font-size: 1.3em;
    font-weight: 600;
    margin: 0 0 5px;
    padding: 0;
    text-align: left;
  }
  
  ul#menu li {
    display: inline;
    list-style: none;
    padding-left: 15px;
    float: left;
  }
  
  ul#menu li a {
    background: none;
    color: #FFF;
    text-decoration: none;
  }
  
  ul#menu li a:hover {
    color: #FFF;
    text-decoration: none;
  }
  
  ul#menu ul {
    display: none;
  }
  
  ul#menu li {
    display: inline;
  }
  
  ul#menu li:hover ul {
    display: block;
  }
  
  ul#menu li:hover ul li a {
    display: block;
    color: red;
  }
  </code></pre>
  
  <p>I have it to the point where I can toggle the colour when hovered over the main menu items, but just can't get them vertical. </p>
