Many thanks for the help!
>>2. I understand what you mean by hierarchical data, but don't understand what you mean by "data-aware tree module." If this data is in filemaker, you can create a relationship within the file between the ID field and the ParentID field; then use a portal to display child info right in filemaker.<<
Most often you can edit the trees but they are not "data-aware". You can not link them to a table that has the fields itemID and parentID. I am looking for a tree I can link to a table.
