You can use like this example of menus drop down if you want to use for catagories use appropriate tables (for radios use level field of table as main in ul,ol indteadof select ):-

<?php $db = JFactory::getDBO();
      $query = "SELECT m.id, m.title,m.level,mt.menutype FROM #__menu AS m INNER JOIN #__menu_types AS mt ON mt.menutype = m.menutype WHERE mt.menutype = m.menutype AND m.published = '1' ORDER BY mt.menutype,m.level";
      $db->setQuery($query);
      $rows = $db->loadObjectList();?>

      <select id="setredirct" name="settings[]">
        <option value="" selected="selected">---Default---</option>
        <?php foreach ($rows as $row) {?>
        <option value="<?php echo $row->id;?>" >
          <?php echo '<b>'.$row->menutype.'</b>';
          if ($row->level == 1) { echo '-';}
          if($row->level == 2) { echo '--';}
          if($row->level == 3) { echo '---';}
          if($row->level == 4) { echo '----';}
          if($row->level == 5) { echo '-----';}
            echo $row->title;?>
        </option>
      <?php }?>
      </select>
