Модуль:DependencyList

This template is meant to be used on module documentations.

{{DependencyList|<<Module name>>}}

All parameters are optional. If Module name is omitted the page name will be used instead; /doc is automatically removed.

If category is false then no categories will be added to the page, the default value is true.

If compact is true links will be separated by commas instead of every link on a new line.

Examples

{{DependencyList|<Module:For>}}

{{DependencyList|<Module:Infobox>}}
