Table of Contents


Since 3.0

The ace:rowExpansion renders a set of rows located underneath the row where ace:expansionToggler was activated. These subrows are defined by a tree relationship modeled in the List bound to the 'value' attribute of the parent DataTable. The List must be of the type List<java.util.Map.Entry<Object, List>> where the entries are mappings from row data objects to lists of sub-entries. If your application is using Java 6, java.util.AbstractMap.SimpleEntry<K,V> is available as a implementation of Map.Entry.

See the ICEfaces Showcase Live Demo of this component, complete with source code.
