Nested Entries in Craft 3

Question

In Craft 2 there used to be a Nested Entries field, but this is not available in Craft 3.

I know I can do {parent.uri}/{slug} in the Entry URI Format field, but if I want it to be appended by something static it doesn't work.

i.e. static/{parent.uri}/{slug} doesn't work because children uri sets to static/static/parent/child (edited)

Answer 1

I kind of found a work around, but doesn't seem like it's the correct way to be doing this.

{parent.uri ? parent.uri : 'static'}/{slug}

Answer 2

Reviving this quite late, but the docs state the following as the correct method:

{parent.uri}/{slug}
