        return self.mainquestionViewModel.numberOfSections()

    }


    func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {

        let cell = verticalCollectionView.dequeueReusableCell(withReuseIdentifier: "NH_MainHeader", for: indexPath)as!  NH_MainHeader

        cell.tableView.dataSource = self

        cellTypes = [.NHCheckBoxCell, .NHRadioTypeCell, .NHSmileyTypeCell, .NHStarRatingTypeCell, .NHTextTypeCell,.NHDatePickerTypeCell]

        for type in cellTypes{
            cell.tableView.registerNibForCellClass(type.cellType().getClass())
        }


        cell.setReviewData(reviews:self.mainquestionViewModel.titleForHeaderInSection(atsection: indexPath.row))

        return cell
    }

        print(model.answerType)

        print(model.answerType?.rawValue)
        let c = model.answerType
        return c!.cellType().getHeight()
    }



    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

         let model = self.mainquestionViewModel.titleForHeaderInSection(atsection: indexPath.section)

        print(model.options)

        print(model.answerType)

        let optionModel = self.mainquestionViewModel.datafordisplay(atindex: indexPath)


        let cell = tableView.dequeueReusableCell(withIdentifier: (cellClass?.cellReuseIdentifier())!, for: indexPath) as! BaseCell


//      cell.setOptions(Options1:model.optionsModelArray[indexPath.section])

        cell.setOptions(Options1:self.mainquestionViewModel.datafordisplay(atindex: indexPath))

        cell.selectionStyle = .none
              return cell

        let c = model.answerType
        let cellClass = c?.cellType().getClass()
        print(cellClass)

        let optionModel = self.mainquestionViewModel.datafordisplay(atindex: indexPath)


        let cell = tableView.dequeueReusableCell(withIdentifier: (cellClass?.cellReuseIdentifier())!, for: indexPath) as! BaseCell
