Get the option value row Id from a display tag table on a jsp, into a struts 1

Question

I am using display tag to display data in a table on a JSP. I want to display a dropdown within display table tag.

My jsp structure and what I am currently trying is :

In property suggestedValueList data is coming in the list form in dropdown How can I separate the values in dropdown

this is my action class code to get the Suggestedvalue list

    public void createErrText(int m, String superType, HCP hcp2, ArrayList<String> HCPsuggestedValueList) {
    superType = superType.trim();
    if (superType.equals("PROF")) {
            HCPsuggestedValueList.add(superType + " HCP ID: " + hcp2.getHcp_id() + ", " + hcp2.getFirst_name() + " "
                    + hcp2.getLast_name() + ", " + hcp2.getAddress1() + " " + ", " + hcp2

            HCPsuggestedValueList = (ArrayList<String>) HCPsuggestedValueList.stream()

    } else {
            HCPsuggestedValueList.add(superType + " HCP ID: " + hcp2.getHcp_id() + ", " + hcp2.getName() + ", "

            createErrText(m,hcp.getSuper_type(), hcp2, HCPsuggestedValueList);
        }
    System.out.println("***inside add hash error :: recordno is****"+recordNo);
        addError(inner, recordNo, hcpType, "Incorrect ID and Name/Address Combination",
                "Incorrect " + hcpType + "ID and Name/Address Combination",hcp.toString(),"", HCPsuggestedValueList);
  }

This is the my Bean class

after uploading the excel file we fetching the data in action class and generating the error after validation.

How can I display dropdown values for selected record number?
