title: Hide HTML with PHP conditional - Not working
body: <p>I am very new to PHP and I am trying to get a piece of PHP code to run inside of my HTML file.</p>
  
  <p>I have a drop down menu.  If users select one item, it should display additional fields.  So, I want them to only display if they select that item from the drop down menu.  I am trying to select it based on the value for that drop down item. I have not declared any PHP values in a PHP script.  This is all in HTML.</p>
  
  <p>I know that with jquery you have to pull in the jquery library before running the script.  Do I need to do this with PHP also?</p>
  
  <p>Here is the code that I am trying to run:</p>
  
  <p>Thank you in advance!</p>
  
  <pre><code>&lt;?php
    if ($dropmenuValue == "specificParameter") {
  ?&gt;
    &lt;div&gt;
      -conditional content-
    &lt;/div&gt;
  &lt;?php
    }
  ?&gt;
  </code></pre>
