Summary of Changes

This Pull Request fixes an issue where select options with the text value 0 were treated as empty.

The select option helper previously used a truthy check on trim($text), which means the string 0 was considered empty by PHP. As a result, when an option was created with text 0, Joomla used the option value as the displayed text instead of preserving the provided text.

The check now explicitly tests for an empty string, so 0 remains a valid option text.

Testing Instructions

1. In the administrator backend, create a category with the title '0'.
2. Go to Content -> Articles.
3. Open the category filter dropdown labeled '- Select Category -'.
4. Check the entry for the category created in step 1.

Actual result BEFORE applying this Pull Request

The category entry is displayed using the category id instead of the category title 0.

Expected result AFTER applying this Pull Request

The category entry is displayed correctly with the category title 0.
