How long should a list item be?

Can a list item have have more than one paragraph? if so, how many is the maximum recommended? and when that type of lengthy list item is used? Is there a difference in length between bullet and numbered list items?

I've never seen a list item of more than one paragraph, so I'm curious if they actually exist or are must nots.

After reading the answers and comments I clarify that I'm not referring to nested lists.

Solution 1:

There are no prescribed lengths for list items in English. They can have breaks - these are often seen in nested lists.

Legislation and other legal documents, for example, can have lengthy list items.
