Module:Labelled list hatnote provides a handful of functions that make it easy to implement hatnotes that take the form of a label in front of a list of pages. See Module:Labelled list hatnote on Wikipedia for more details.
--------------------------------------------------------------------------------
-- Labelled list --
-- --
-- This module does the core work of creating a hatnote composed of a list --
-- prefixed by a colon-terminated label, i.e. "LABEL: [andList of pages]", --
-- for {{see also}} and similar templates. --

local defaults = {

labelForm = '%s: %s',
prefixes = {'label', 'label ', 'l'},
template = 'Module:Labelled list hatnote'
}
-- Helper function that pre-combines display parameters into page arguments.
-- Also compresses sparse arrays, as a desirable side-effect.
function p.preprocessDisplays (args, prefixes)
-- Prefixes specify which parameters, in order, to check for display options
-- They each have numbers auto-appended, e.g. 'label1', 'label 1', & 'l1'
prefixes = prefixes or defaults.prefixes

end
end

end
-- Produces a labelled pages-list hatnote.
-- The main frame (template definition) takes 1 or 2 arguments, for a singular
-- and (optionally) plural label respectively:
-- * {{#invoke:Labelled list hatnote|labelledList|Singular label|Plural label}}
-- The resulting template takes pagename & label parameters normally.
