How to attach an item to a mob/block/another item

[Swagcrafters 2]

How can I attach an item to a mob/block/another item? I know there used to be an option to attach an item to a mob but I discovered that years ago and I can't find it inside the software anymore. Has it been removed?

Edit: Thanks to Vollo and 9redwoods, I learnt two ways to do it. Thank you. I'll be able to create much more stuff with the ability of attaching stuff to each other

On the right tab, (should say "item properties") you'll find a drop-down that says "parent." Click that and choose an object to parent the other object to.

On the timeline, just click and drag the item on top of whatever body part/block/item you want to attach it to.
