Minting Types are compatible with Placeholder. For instance, you can use Specify Minting along with Placeholder to temporarily hide the metadata, and reveal at a later time.
Using this minting type, NFTs are minted and chosen by the user itself. If you don't use a placeholder is a way to let you users choose the NFTs they like.
Despite being possible, it is not recommended for very large collections as it may difficult the user to choose the desired NFT.
