documentation FilteringSelect queryExpr with formatter example

[hvierendeels]

Maybe it can be useful to others:
One can enrich queryExpr with formatter

example:
queryExpr:'${0:String.toUpperCase}*'

<select data-dojo-type="dijit.form.FilteringSelect" ....data-dojo-props=".,queryExpr:'${0:String.toUpperCase}*'," ..../>
