Problem:
The client is experiencing issues with the MegaMenu on a multilingual WordPress site using WPML. In the German version, the Products menu item shows categories but no products, and clicking on a category leads to an incorrect URL.
Solution:
1. We reviewed the MegaMenu code and found that the product categories were added but were pointing to the wrong URLs. We updated the code to be language-aware by adding a WPML language parameter and setting the language before querying products.
2. We also checked the slug translation issue and found that WordPress does not allow duplicate slugs across languages, which is not controlled by WPML.
3. We recommended setting up a staging site and activating a default WordPress theme to confirm if the issue is caused by the custom menu walker in the theme. If the problem persists, it may require custom development.
