Problem:
You are trying to display categories as a drop-down list on the translated Thai property page using WPML, but the categories do not display at all, unlike the English page where they appear correctly.
Solution:
1. Ensure that all categories are fully translated. Navigate to WPML > Taxonomy Translation, select categories from the drop-down menu, and verify that all categories are translated. For more information, visit Translating Post Categories and Custom Taxonomies.
2. Confirm that the widget used to display the categories is translated. This can be done using the String Translation or by using a separate widget for each language. Detailed guidance can be found here: Translating Widgets.
3. Check for any known compatibility issues that might be affecting the display of categories. Currently, there is an open issue related to this problem, which can be tracked on the WPML Errata page: WP Residence - No Results Found in Advanced Search.

If these steps do not resolve your issue or if the solution becomes outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If the problem persists, please open a new support ticket.
