Using muliple fields in a filter widget.

LucasRosen

 

I am using the Filter Widget in a Mapping Application. I currently have two maps: one for the 2D Townships  (Subdivisions) and one for the 1D Township Boundaries (Exteriors). I am trying to allow the user to filter (called "Township Inquiry") by Township, Range, and Range Direction. It works for the Subdivisions but not for the Exteriors because the Exteriors cover more than one township (see images).    

 

 

 

I have another field that has the other half of the township, but the filter won't allow me to select both fields even though the value is the same. Is there a way I can do this?

Regards,

Luke R

Take a look at the Group Filter widget.

As pictured below, add the same layer twice, using the two fields. Make sure you have the option Match any expression chosen. That way, any boundary that has, say, 15 in either field will meet the criteria.

Clicking the "Use Value" radio button will turn the unique values of that field into a dropdown list.

You can add additional groups to have similar filter groups to handle Township, etc. Unfortunately, adding multiple groups to the Group Filter widget doesn't look quite as nice as the regular Filter widget. And if you do add multiple groups, make sure that the option Append all expressions to existing map filter is chosen, otherwise you can only filter one group at a time.

Voila!

Our filter successfully picks up 109 / 110 with the selection of "110".

Hope you don't mind I opened a copy of your app to test my ideas.
