Can you help me transform an unordered list that looks like this?
<ul class="selectdropdown">
<li><a href="one.html" target="_blank">one</a></li>
<li><a href="two.html" target="_blank">two</a></li>
<ul>
<li><a href="twoOne.html" target="_blank">two One</a></li>
<ul>
<li><a href="twoOneOne.html" target="_blank">two One One</a></li>
</ul>
<li><a href="twoTwo.html" target="_blank">twoTwo</a></li>
</ul>
<li><a href="three.html" target="_blank">three</a></li>
<li><a href="four.html" target="_blank">four</a></li>
<li><a href="five.html" target="_blank">five</a></li>
<li><a href="six.html" target="_blank">six</a></li>
<li><a href="seven.html" target="_blank">seven</a></li>
</ul>
I need to change this layout into a <select>
structure
