Where is the Card Deck component?

I don’t find the “card deck” option anymore.
Has it been deleted or just moved ?

Even if i manually create a div with “card-deck” class, the render doesn’t show it properly

There is no card-deck class in bootstrap 5
In bootstrap 5 give each card a class h-100:
if you want to use the class card-deck in your design it must be a bootstrap 4 design
