Enhanced Category Widget Flexibility

I’d like to suggest an enhancement for the category widget. Currently, it only allows selecting first-level categories, and the main categories and they cannot be reorganized. It would be very useful if the widget could:

1. Include second- or third-level subcategories so users can find popular areas faster.

2. Allow reordering of categories and subcategories, giving admins control over display order to optimize user navigation and experience.

This improvement would make the directory more flexible, easier to navigate, and allow highlighting of the most relevant subcategories for users, improving both discoverability and engagement.
