Template:Navlist/Link subpage
Usage
[edit source]Takes one optional, unnamed parameter. If the parameter is non-blank, and the transcluding has a subpage with that name, produces a link to that subpage, with the parameter as its label, i.e., [[{{FULLPAGENAME}}/{{{1}}}|{{{1}}}]]. If the parameter is blank or the subpage doesn't exist, produces blank (the empty string, with no whitespace).
