Afk spider farm help

[Secruts]

Looking to see if anyone has a afk spider / cave spider farm, in the form of a dropper farm, tried some ideas myself and couldn't get it to work properly, tried looking on youtube as well and couldn't find much, mainly looking for item farm not xp, any ideas would be great, Thank you!
