As Jean-Noel said, if you really want to get a particular element, you
don't want to use iterate. But if what you are actually looking for is
how to get the index of the current element inside an iterate block, I
think you need to manage that separately. It's not ideal, but here's
what I do to produce a table with alternately shaded rows:
<% int rowNumber = 0; %>
<logic:iterate id="ddItem" name="dropdownItems">
<% if( ( ++rowNumber % 2 ) == 1 ) { %>
<tr class="listViewOdd">
<% } else { %>
<tr class="listViewEven">
<% } %>
<td>...</td>
<td>...</td>
<td>...</td>
</tr>
</logic:iterate>
It would be nice if interate also made an index available, but you can
do something like that as a work-around for now (unless someone has a
better suggestion).
