Opencart更改类别链接

I want to edit the parent category link, at the moment it doesn't do anything except display the dropdown menu, anyone know how to edit this?

Just a Hint, the code you are interested in (navigation bar of the categories) is written at the same files of the header:

• Open the file <OC_ROOT>/catalog/view/theme/<Your_Theme_Folder>/template/common/header.tpl
• Find the loop that prints categories, in all versions of OC it looks like:
  <?php foreach ($categories as $category) { ?>
• That's it, now you just need to change HTML of parent categories, they are printed inside a code block that looks like:
  <?php if ($category['children']) { // here } ?>

Give it a try and I'll be here if you still have a problem
