        cell?.contenLabel?.text = dataSouce[indexPath.row].name //Text
        cell?.iconImageView.image = UIImage(named: dataSouce[indexPath.row].value!) //Image

        //Selected properties
        cell?.tintColor = option.checkMarkColor
        if indexPath == lastSelectedIndexPath {
            cell?.accessoryType = .checkmark
        } else {
            cell?.accessoryType = .none
