I wanted to come back to this to get some further direction outside of the information lookup template. Web App Builder is where I am likely going to want to do this for in a particular service layer at some point. Again, looking for some insight.
I was first thinking that maybe I could do a vector cache on the polygon layer and then associate just the features for popups? I think I heard that can be done. Although maybe that would still show a selection, not sure. Basically, will want the popup field attribute information to appear upon address search or upon map click like the information lookup template. Obviously I will want these results to pop up upon the search widget's finding of an address (presuming the widget's code will need to be modified in some way? although that's another issue). Once it does, I do not want the field attribute results showing selected boundaries.
I suppose examining the information lookup template javascript code could maybe get me some insight, but I am big time newcomer at anything with javascript at the moment.
Thanks.
