You can use this:

<html-el:select property="Reports" >
<c:forEach var="curmyMap" items="${myMap}">
<html-el

ption value="${curmyMap.key}"><c

ut value="${curmyMap.value}"/></html-el

ption>
</c:forEach>
</html-el:select>

It should also work with html:select....

This should also work:

<html:options collection="myMap" property="key" labelProperty="value" />

When Struts iterates through any implementation of the java.util.Map interface, each entry is of type Map.Entry, which has a key and a value property.
