You don't. Change mw-customtoggle-(1, 2, 3) to mw-customtoggle- (1, 2, 3). Then use template: LyricsFAN|id=someid1, LyricsFAN|id=someid2 etc.

id="mw-customcollapsible-(1, 2, 3)" have to be changed too: id="mw-customcollapsible- (1, 2, 3)"

Something like that: ! style="text-align:center; font-size:small;" | ⇵ Japanese ⇅ |- class="mw-collapsible mw-collapsed" id="mw-customcollapsible-1"
