Hi, welcome to OpenZeppelin.

You have to implement a random feature that picks an id between number of NFTs.
Where is the code you are working with?

Hey thanks for reply im using one of the hashlips repositories. Here is the code: https://github.com/HashLips/solidity_smart_contracts/blob/main/contracts/NFT/NFT.sol

How can i implement random feature. I have no idea at all... Can you PLEASE help me about that? I really want to learn how to do this and its important to me.

you can have a public function that state the exact id you want or randomize it and can be generated onClick.

something like:

function mintRandomly() public{
  uint tokenID = /*randomly generate an ID that is within the totalSupply*/
 _safeMint(to, tokenID)

Randomness in smart contracts is difficult to achieve. There is a lot written about this, even in this forum. Please search the forum and the web for "NFT randomization" or similar.
