Do Moves/Abilities have a certain Priority?

Question

Well, I was testing this Question with Mew on Pokemon Showdown, and I saw that Sturdy, at times, was not activating before Focus Band (I was using Level One Pokemons). Which go me thinking...

Do Items have a certain priority, just like moves?
If so...
Are there specific items that will activate before an Ability?

Wow I can't find anything on that. I would say yes because Quick Claw allows your pokemon to move forst and then there is all the healing items.

There isn't a list or anything that I can find though.

Answer 1

Quick Claw is the only Item that activates before an ability, but no, Items do not have a Priority.
