To include a list facet, add to your HTML

 <div ex:role="facet" 
   ex:expression=".property">
 </div>

Replace .property with the appropriate expression for your exhibit.

Other settings supported include:

setting name	type of value	default	choices	meaning
ex:facetLabel	text			what to show in the header of the facet
ex:height	text			height of the facet's body, e.g., "20em", "200px"
ex:sortMode	text	value	"value", "count"	how to sort the choices in the facet
ex:sortDirection	text	forward	"forward", "reverse"	whether to reverse the sort direction
ex:showMissing	text	true	"true", "false"	whether to provide a selection for items missing the facet -- this will suppress the '(missing this field)' text
ex:selection	text			semicolon-separated list of default selections
ex:fixedOrder	text			semicolon-separated list of values specifying a fixed order for sorting the choices in the facet, e.g., "Mo;Tu;We;Th;Fr" for weekdays
ex:scroll	text	true	"true","false"	if true, facet values are in a scrollable window of fixed size. If false, all facet values are shown in as much space as needed, without a scroll bar.

Note that when ex:sortMode="count", the facet lists highest counts at the top. But with ex:sortMode="value" the lowest values are at the top. Either way, ex:sortDirection will reverse the direction.
