Nested Entries in Craft 3 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)
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}
