HotCat, znany także jako CategorySelect[1] (CS) to narzędzie ułatwiające kategoryzację artykułów. Jest standardowe dla skórki domyślnej, zaś dla Monobooka potrzebny jest specjalny kod instalujący tę funkcję.

CategorySelect w skórce domyślnej

Funkcja ta na skórce domyślnej znajduje się u dołu artykułu. Klikając przycisk Dodaj kategorię można skategoryzować artykuł nie otwierając okna edycji całej strony. Niestety, aby usunąć lub zmienić kategorię należy przejść do edycji całego artykułu.

Uruchamianie CS bez edycji artykułu. Po lewej przed kliknięciem, po prawej po kliknięciu w przycisk Dodaj kategorię


Używać CategorySelect można również podczas edycji artykułu, lecz tylko w trybie wizualnym. Narzędzie znajduje się wówczas w prawym panelu, w sekcji Kategorie. Można tutaj dodać kategorię, a także usunąć lub zmienić istniejące. Podczas wprowadzania kategorii pojawiają się sugestie pomocnicze, czyli nazwy istniejących już kategorii o początkach takich, jakie już zostały wprowadzone, w kolejności alfabetycznej. Na przykład, po wpisaniu początku kategorii frazy Pi podpowiedziach zostaną wyświetlone istniejące kategorie zaczynające się na Pi, czyli przykładowo Pierogi, Pieniądze, Piaski w kolejności alfabetycznej.

Aby wyświetlić kategorie w postaci kodu, należy przejść do trybu źródłowego.

HotCat w Monobooku

HotCat działa na tej samej zasadzie co CategorySelect, jednakże można usuwać i zmieniać kategorie bez potrzeby edytowania artykułu. Aby uruchomić to narzędzie, należy na stronie Special:Mypage/Monobook.js zaaplikować odpowiedni kod. Jeden z takich dostępny jest poniżej:

  * HotCat: Łatwy sposób na dodawanie, modyfikację i usuwanie kategorii
  * Dokumentacja: [[:en:User:TheDJ/HotCat]]
  * Autor: Magnus Manske
  * 
  * This version was forked from http://commons.wikimedia.org/w/index.php?title=MediaWiki:Gadget-HotCat.js&oldid=10204404
  * Major changes:
  *   - blacklist code is disabled.
  *   - all code for the uploadForm has been removed
  *   - autocommit is disabled
  *   - will be enabled on pages without categories so that you can easily add them
  *   - uses javascript:void() as a dummy value for href in order to avoid a conflict with popups.
  *   - checks for {{Uncategorized}} and removes it if a category is added
  *   - does not use JSconfig for configuration options like its Commons original
  *   - tries to detect other categories and if possible, add to the end of them.
  *   - fixes a bug in the suggestion list with titles containing : character
