Guys found the solution Check the usage of nested tags that can handle any levels.

Top most element is ModulesList= it has N modules Module = it has N Parts Part= it has N Elements Here is the class hieirarchy Parent class that holds all modules. public class FSModuleListForm extends ActionForm { private List mModuleList = new ArrayList(); public List getModuleList() {return mModuleList;} public void setModuleList(List aModuleList) {mModuleList=aModuleList;} public FSModuleForm getModule(int index) { return (FSModuleForm) mModuleList.get(index); } public void reset(ActionMapping aMapping, HttpServletRequest aRequest) { super.reset(aMapping, aRequest); moduleList = new ArrayList(); for (int i=0; i < 25; i++) { mModuleList.add(i, new FSModuleForm()); } } } ============================================== //Module Description public class FSModuleForm extends ActionForm { Public FSModuleForm() { moduleId = -1; moduleName=null; moduleType=null; moduleLabel=null; partsList = new ArrayList(); //Lets initialize the list for (int i= 0 ; i < 10; i++ ){ partsList.add(i,new FSPartForm()); } } public FSPartForm getPart(int index) { return (FSPartForm) partsList.get(index); } public void reset(ActionMapping aMapping, HttpServletRequest aRequest) { partsList = new ArrayList(); //Lets initialize the list for (int i= 0 ; i < 10; i++ ){ partsList.add(i,new FSPartForm()); } } } ============================================== // PART Description public class FSPartForm extends ActionForm { public FSPartForm() { partId=-1; sortOrder=0; partName=null; partLabel=null; partType=null; optionalFlag=null; partFootnote=null; elementList= new ArrayList(); //Lets initialize the list for (int i= 0 ; i < 20; i++ ){ elementList.add(i,new FSElementForm()); } } public FSElementForm getElement(int index) { return (FSElementForm) mElementList.get(index); } public void reset(ActionMapping aMapping, HttpServletRequest aRequest) for (int i= 0 ; i < 50; i++ ){ elementList.add(i,new FSElementForm()); } } } ============================================== //Elemet Description. public FSElementForm extends ActionForm { public FSElementForm() { elementId=-1; elementName=null; elementType=null; optionalFlag=null; defaultValue=null; sortOrder=0; } } Here is my JSP <logic:iterate id="module" name="FSModuleListForm" property="moduleList"> <tr> <tr > <!—Module info → <bean:write name="module" property="moduleName" /> <tr> Desc:<html:text name="module" property="moduleDesc" indexed="true" /> Label:<html:text name="module" property="moduleLabel" indexed="true" /> <html:hidden name="module" property="moduleId" indexed="true" /> </tr> <logic:present id="part" name="module" property="partsList"> <logic:iterate id="part" name="module" property="partsList"> <tr> <tr><bean:write name="part" property="partName" /></tr> <tr>Label:<html:text name="part" property="partLabel" indexed="true" /></tr> <html:hidden name="part" property="partId" indexed="true" /> </tr> <!—code to get each element will go here → </logic:iterate> </logic:present> </tr> <hr> </logic:iterate> ISSUE: 1. Should I extend actionform for all classes or just the top most class is good (in my eg FSModuleListForm) ? 2. I am able to display data on screen but when I submit only the module information gets populated Not the parts associated to each module. Though indexing value displayed looks good. Html generated some what looks like InvestMent Objective1: Desc: <input type="text" name="module[0].moduleDesc" value="InvestMent Objective – first "> Label:<input type="text" name="module[0].moduleLabel" value="InvestMent Objective First"> <input type="hidden" name="module[0].moduleId" value="1"> This is Investment Objective1 Part NAME Label:<input type="text" name="part[0].partLabel" value="This is Investment Objective1 Part Label"> <input type="text" name="part[0].partId" value="1"> ---------------------------------------------------------------------- InvestMent Objective2: Desc: <input type="text" name="module[0].moduleDesc" value="InvestMent Objective – Second "> Label:<input type="text" name="module[0].moduleLabel" value="InvestMent Objective second"> <input type="hidden" name="module[0].moduleId" value="2"> This is Investment Objective2 Part NAME Label:<input type="text" name="part[0].partLabel" value="This is Investment Objective2 Part Label"> <input type="text" name="part[0].partId" value="2"> Can some one please help me on this issue or is this not possible in Struts ? Thanks in advance. Warm Regards Ramachandra Reddy
