MediaWiki:Visualdata-jsmodule-formfield-query-help

Enter a visualdata query (wikitext and parser functions allowed). Use <property name> to retrieve the value of other fields in the same form (if a nested property use the complete path separated by slashes and omit array indexes for multiple items) and <value> (use as it is) to use the current value of the input. With the LookupElement or MenuTagSearchMultiselect (the latter only available if the field is multiple) widgets a standard query is [[<property name>::<value>~]] (replace "<property name>" with the retrieved printout).
