Javascript Form Validation issue how to reveal condition input field : <p>I'm using Bootstrap and Vanilla Javascript. It is a very simple form, really. </p>

<p>My problem, as I have not done any Javascript in a few years, is how to get around the first thing I need help about.</p>

<p>Now to the problem:</p>

<pre><code>IF the user select "Near_death" in the drop down. a new form must be shown. This has been hidden as long as no one chooses "Near_Death". Such as.

&lt;div class="form-group"&gt;
   &lt;select id="types" name="types" class="form-control"&gt;
   &lt;option value="Near_death"&gt;Near_death&lt;/option&gt;
   &lt;option value="1" type="number"&gt;1&lt;/option&gt;
   &lt;option value="2" type="number"&gt;2&lt;/option&gt;
   &lt;option value="3" type="number"&gt;3&lt;/option&gt;
     &lt;/select&gt;
 &lt;/div&gt;
</code></pre>

<p>I expect the lower form to revel itself if the user check the "Near_death" form option. It's just a case of conditional hide/show but I cannot for the life if me remember how I used to do it.</p>

<p>Please, Only Vanilla JavaScript. Thank you all for any help. Much appreciated! :=)</p>
