Moglibyśmy wyświetlać obrazy w galerii za pomocą krótkiego kodu w ten sposób . Chciałbym osiągnąć to samo, ale dla kategorii. Mam krótki kod, który wyświetla wszystkie warunki niestandardowego typu postu o nazwie „theme_portfolio_image”. Chcę, aby wyświetlały się tylko wybrane/określone kategorie.

Oto mój krótki kod

[portfolio columns=”3″ title=”My Title”] ale chciałbym to wykorzystać w ten sposób

[portfolio columns=”3″ title=”My Title” ids=”20,22,30,35″]

każda pomoc byłaby mile widziana
