### Override expand state rules for menu entries
|
||||
|
||||
You can change how the theme expands menu entries on the side of the content with the `alwaysopen` setting on a per page basis. If `alwaysopen=false` for any given entry, its children will not be shown in the menu as long as it is not necessary for the sake of navigation.
|
||||
|
||||
The theme generates the menu based on the following rules:
|
||||
|
||||
- all parent entries of the active page including their siblings are shown regardless of any settings
|
||||
- immediate children entries of the active page are shown regardless of any settings
|
||||
- if not overridden, all other first level entries behave like they would have been given `alwaysopen=false`
|
||||
- if not overridden, all other entries of levels besides the first behave like they would have been given `alwaysopen=true`
|
||||
- all visible entries show their immediate children entries if `alwaysopen=true`; this proceeds recursivley
|
||||
- all remaining entries are not shown
|
||||
|
||||
You can see this feature in action on the example page for [children shortcode]({{< relref "shortcodes/children" >}}) and its children pages.

|

|

Use the children shortcode to list the child pages of a page and the further descendants (children's children). By default, the shortcode displays links to the child pages.
