Question

Is it possible to display the elements of a list in a list with a foreach in a jsp?

List<List<String>> elements;

i was thinking something like :

<c:forEach var="charge" items="${customerOfferForm.offersWithCharges.get(0)}">

Your syntax will work in EL 2.2 (which is available since Servlet 3.0 containers such as Tomcat 7, Glassfish 3, etc), but not in older versions. You can then use the brace notation [] to get the desired list item by index.

<c:forEach items="${customerOfferForm.offersWithCharges[0]}" var="charge">
    ...
</c:forEach>

You can if necessary use a nested <c:forEach> to display all items.

<c:forEach items="${customerOfferForm.offersWithCharges}" var="offerWithCharges">
    <c:forEach items="${offerWithCharges}" var="charge">
        ...
    </c:forEach>
</c:forEach>
