OpenCart Filtergroup下拉列表

Question

How can I make a dropdown for a specific filtergroup id only? I need the other filtergroups to stay like the default list.

On template/module/filter.tpl

I have added

<select id="select-filter-group<?php echo $filter_group['filter_group_id']; ?>">
        <option value=""><?php echo $text_select; ?></option>
        <?php foreach ($filter_group['filter'] as $filter) { ?>
          <?php if (in_array($filter['filter_id'], $filter_category)) { ?>
            <option value="<?php echo $filter['filter_id']; ?>" selected="selected"><?php echo $filter['name']; ?></option>
          <?php } else { ?>
            <option value="<?php echo $filter['filter_id']; ?>"><?php echo $filter['name']; ?></option>
          <?php } ?>
        <?php } ?>
        </select>

This works but makes every filtergroup into a dropdown, I just need Filter Group ID 4 (exmaple) to be a dropdown and the other stays as before.

How can this be done?

Then, very simply, use a condition around Your select:

<?php if($filter_group['filter_group_id'] == 4) { ?>
  <select id="select-filter-group<?php echo $filter_group['filter_group_id']; ?>">
    <option value=""><?php echo $text_select; ?></option>
    <?php foreach ($filter_group['filter'] as $filter) { ?>
      <?php if (in_array($filter['filter_id'], $filter_category)) { ?>
        <option value="<?php echo $filter['filter_id']; ?>" selected="selected"><?php echo $filter['name']; ?></option>
      <?php } else { ?>
        <option value="<?php echo $filter['filter_id']; ?>"><?php echo $filter['name']; ?></option>
      <?php } ?>
    <?php } ?>
    </select>
<?php } else { ?>
<!-- the default code for filter groups goes here -->
<?php } ?>
