List of Map objects with html:options collection

Question

Hello All,
I'm trying to get an arraylist of map objects to display dynamically as a dropdown select with html:options collection. I've spent hours on this and I haven't been able to get it working. Any ideas as to how this is done?
Thanks,
James

An arraylist of Map objects?
What is it that you want to show up in the dropdown box - all the name value pairs included in all the maps of the list?
Assuming with a Map the "key" is what you want submitted and the "value" is what to display to the user
Definitely sounds like a double loop structure is required. One to loop through all the maps. Another to generate all the options in each map.
This one does it at the basic level of things
<c:forEach var="map" items="${listOfMaps}">
  <c:forEach var="entry" items="${map}">
    <html:option value="${entry.key}">${entry.value}</html:option>
  </c:forEach>
</c:forEach>The following might also work.
<c:forEach var="map" items="${listOfMaps}">
  <html:options collection="map" property="key" labelProperty="value"/>
</c:forEach>Cheers,
