===Nesting Navboxes to get more groups/lists===
You can conveniently nest Navboxes, including {{tl|Navbox with collapsible groups}}, to get an unlimited number of groups/lists.  The following example uses one instance of {{tl|Navbox with collapsible groups}} to get the first 10 collapsible groups, a nested instance to get the next 10, and another nested instance to get the last 6.  See the code to learn how it works.  It is fairly simple to extend this to as many groups/lists as you like:

{{Navbox with collapsible groups
|name = {{PAGENAME}}
|state = collapsed
|title = Title
|selected = {{{1|}}}

|group1 = A
|list1 = List A
|group2 = B
|list2 = List B
|group3 = C
|list3 = List C
|group4 = D
|list4 = List D
|group5 = E
|list5 = List E
|group6 = F
|list6 = List F
|group7 = G
|list7 = List G
|group8 = H
|list8 = List H
|group9 = I
|list9 = List I

|list10 = {{Navbox with collapsible groups|child
  |selected = {{{1|}}}

  |group1 = J
  |list1 = List J
  |group2 = K
  |list2 = List K
  |group3 = L
  |list3 = List L
  |group4 = M
  |list4 = List M
  |group5 = N
  |list5 = List N
  |group6 = O
  |list6 = List O
  |group7 = P
  |list7 = List P
  |group8 = Q
  |list8 = List Q
  |group9 = R
  |list9 = List R

|list10 = {{Navbox with collapsible groups|child
  |selected = {{{1|}}}

  |group1 = S
  |list1 = List S
  |group2 = T
  |list2 = List T
  |group3 = U
  |list3 = List U
  |group4 = V
  |list4 = List V
  |group5 = W
  |list5 = List W
  |group6 = X
  |list6 = List X
  |group7 = Y
  |list7 = List Y
  |group8 = Z
  |list8 = List Z
