## 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|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). 


### Example


[[!format txt """
 * HelpOnEditing/SubPages
 * [wiki:HelpOnEditing/SubPages This very page]
 * [wiki:Self:HelpOnEditing/SubPages This very page]
 * /ThirdLevel
 * [wiki:/ThirdLevel A page below this one]
 * ../SubPages
 * ["../"] (anonymous parent link)
 * [:../:free parent link]
"""]]
 


### Display

* HelpOnEditing/SubPages 
* [[This very page|HelpOnEditing/SubPages]] 
* [[This very page|HelpOnEditing/SubPages]] 
* [[/ThirdLevel|HelpOnEditing/SubPages/ThirdLevel]] 
* [[A page below this one|HelpOnEditing/SubPages/ThirdLevel]] 
* ../SubPages 
* [[../|HelpOnEditing]] (anonymous parent link) 
* [[free parent link|HelpOnEditing]] /!\ Please do all of us a favour and don't create the [[/ThirdLevel|HelpOnEditing/SubPages/ThirdLevel]] pages, it's just an example!
