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