title: How do I remove options from a dropdownlist in javascript?
body: <p>Are there any examples out there that will allow me to remove options from drop down list using JavaScript?</p>
  
  <p>Here is the code:  </p>
  
  <pre><code>&lt;select autocomplete="off" id="sSec1" tabindex="0" name="sSec1" class="isSelected styled security selectOriginal"&gt;
        &lt;option id="" value=""&gt;Select&lt;/option&gt;
        &lt;option id="o1" value="What is the name of your first pet?"&gt;What is the name of your first pet?&lt;/option&gt;
        &lt;option id="o2" value="What is your favorite food?"&gt;What is your favorite food?&lt;/option&gt;
        &lt;option id="o3" value="What is your favorite holiday?"&gt;What is your favorite holiday?&lt;/option&gt;
        &lt;option id="o4" value="What is your favorite movie?"&gt;What is your favorite movie?&lt;/option&gt;
        &lt;option id="o5" value="What is your favorite sport?"&gt;What is your favorite sport?&lt;/option&gt;
        &lt;option id="o6" value="In what city were you born?"&gt;In what city were you born?&lt;/option&gt;
        &lt;option id="o7" value="What is your mother's maiden name?"&gt;What is your mother's maiden name?&lt;/option&gt;
      &lt;/select&gt;
  </code></pre>
  
  <p>Here is list 2:  </p>
  
  <pre><code>&lt;select autocomplete="off" id="sSec2" tabindex="0" name="sSec2" class="isSelected security styled"&gt;    
        &lt;option id="" value=""&gt;Select Second Question&lt;/option&gt;
        &lt;option id="o1s2" value="What is the name of your first pet?"&gt;What is the name of your first pet?&lt;/option&gt;
        &lt;option id="o2s2" value="What is your favorite food?"&gt;What is your favorite food?&lt;/option&gt;
        &lt;option id="o3s2" value="What is your favorite holiday?"&gt;What is your favorite holiday?&lt;/option&gt;
        &lt;option id="o4s2" value="What is your favorite movie?"&gt;What is your favorite movie?&lt;/option&gt;
        &lt;option id="o5s2" value="What is your favorite sport?"&gt;What is your favorite sport?&lt;/option&gt;
        &lt;option id="o6s2" value="In what city were you born?"&gt;In what city were you born?&lt;/option&gt;
        &lt;option id="o7s2" value="What is your mother's maiden name?"&gt;What is your mother's maiden name?&lt;/option&gt;
      &lt;/select&gt; 
  </code></pre>
  
  <p>Now what I want to happen is when any option is selected for security question number 1. That option should not be there for security question number 2.</p>
