Thanks MacDonald, It Worked.
I also tried with a map having custom value object as value. below is the example.
public class customVO{
private String customVOAttr;
}
public class customPage extends WCMUse{
private Map<String,customVO> customVOMap;
public Map<String, customVO> getCustomVOMap() {
return customVOMap;
}
}
<div data-sly-list="${customPage.customVOMap.entrySet}">
${item.key} - ${item.value.customVOAttr}
</div>
