随着页头模块 v0.16.0 版本的发布，你现在可以添加三级菜单。
为此，你需要将二级菜单的 identifier 作为三级菜单的 parent。
hugo.toml
1[menu]
2 [[menu.main]]
3 identifier = 'lvl-1'
4 name = 'Level 1'
5 [[menu.main]]
6 identifier = 'lvl-1-2'
7 name = 'Level 1-2'
8 parent = 'lvl-1'
9 [menu.main.params]
10 description = '2nd level menus.'
11 [[menu.main]]
12 name = 'Level 1-2-1'
13 parent = 'lvl-1-2'
14 [[menu.main]]
15 name = 'Level 1-2-2'
16 parent = 'lvl-1-2'
17 [[menu.main]]
18 name = 'Level 1-2-3'
19 parent = 'lvl-1-2'
hugo.yaml
1menu:
2 main:
3 - identifier: lvl-1
4 name: Level 1
5 - identifier: lvl-1-2
6 name: Level 1-2
7 params:
8 description: 2nd level menus.
9 parent: lvl-1
10 - name: Level 1-2-1
11 parent: lvl-1-2
12 - name: Level 1-2-2
13 parent: lvl-1-2
14 - name: Level 1-2-3
15 parent: lvl-1-2
