## Creating Subpages

Subpages are groups of pages that share a common prefix, which itself is another page. While this is also possible with "classic" wiki, by using names like `SomeTopicSubTopic`, the use of `SomeTopic/SubTopic` allows better navigational support, and you can omit the common prefix when linking from the parent page to the child page.

Thus, by using "/" to concatenate several WikiName s, you can create arbitrarily deep hierarchies (within limits, especially the length of filenames on your system). In reality, subpages are normal pages that contain a "/" in their name, and thus they are stored besides all other pages in the file system. Subpages are a configurable feature, but they're on by default and it's recommended that you keep it that way, since the help pages themselves use this feature.

Links to sibling pages start with "`../`", for example ../SubPages (a link to this page).

### 1. Example

     * HelpOnEditing/SubPages
     * [wiki:HelpOnEditing/SubPages This very page]
     * [wiki:Self:HelpOnEditing/SubPages This very page]
     * /ThirdLevel
     * [wiki:/ThirdLevel A page below this one]
     * ["/sub page with arbitrary page name"]
     * ../SubPages
     * ["../"] (anonymous parent link)
     * [:../:free parent link]

### 2. Display

- HelpOnEditing/SubPages

- This very page

- This very page

- /ThirdLevel

- A page below this one

- /sub page with arbitrary page name

- ../SubPages

- ../ (anonymous parent link)

- free parent link

Please do all of us a favour and don't create the /ThirdLevel pages, it's just an example!
