Hi, How to make the script to hide this fields and show up when select the category and subcategory?

      <div id="property-type" class="large-12">
        <label>
          <span class="required_fields">* </span>
          <?php _e('Property Type', 'ctg_housing'); ?>
        </label>
      </div>
        <?php
            $itemtype1 = '';$itemtype2 = '';$itemtype3 = '';$itemtype4 = '';
          if(!empty($s_furnished)){
          if($s_furnished=='bare-unit'){
            $itemtype1 = 'checked = "checked"';
            }
          else if($s_furnished=='unfurnished'){
            $itemtype2 = 'checked = "checked"';
            }
          else if($s_furnished=='semi-furnished'){
            $itemtype3 = 'checked = "checked"';
            }
          else if($s_furnished=='fully-furnished'){
            $itemtype4 = 'checked = "checked"';
            }
          }
        ?>
      <div id="property-type-select" class="large-12">
        <div class="item-post-property-type-0"> 
          <input type="radio" name="s_furnished" id="s_furnished" value="bare-unit" <?php echo $itemtype1;?>>
          <label for="s_furnished">Bare Unit</label>
        </div>
        <div class="item-post-property-type-0">
          <input type="radio" name="s_furnished" id="s_furnished" value="unfurnished"  <?php echo $itemtype2;?>>
          <label for="s_furnished">Unfurnished</label>
        </div>
        <div class="item-post-property-type-1">
          <input type="radio" name="s_furnished" id="s_furnished" value="semi-furnished"  <?php echo $itemtype3;?>>
          <label for="s_furnished">Semi-Furnished</label>
        </div>
        <div class="item-post-property-type-1">
          <input type="radio" name="s_furnished" id="s_furnished" value="fully-furnished"  <?php echo $itemtype4;?>>
