Dropping items in Minecraft is necessary if you want to give or remove some of them from your game inventory. All you need to do is mark the item and press the "Q" key, and the item will be on the ground in front of you. Should you want to pick it up or leave it for another player, it's entirely up to you. When you die in Minecraft, you'll drop all your items and have to start a new game without any of them. This happens automatically, and you can't choose which items you want to save. However, there's a way to change the game rules and ensure that your items list remains unchanged every time you die.
