Template:UI/publications library/facet chip
From Miniscope
Facet-chip partial for Template:UI/publications_library. Receives
the facet value as {{{1}}} and the property name as
{{{userparam}}} (carried through from the #ask
|userparam= argument).
Renders the value as a clickable chip that links to Special:SearchByProperty for that property/value pair — the no-JavaScript way to surface "all publications with this type/topic/ year" without depending on SemanticDrilldown.
The double urlencode on the property name handles the
"+" → "%2B" encoding that SearchByProperty needs (spaces in property
names are encoded as "+" in the userparam, then urlencoded to "%2B"
in the final URL).
