if/else expressions in Arcade / Field Maps to show only certain domain values?

ZacStanley3 — Fri, 02 Apr 2021 19:27:12 GMT

Hi All-

Is it possible in the field maps form to use if/else conditionals to show available fields and/or domains? I’m working on some fire fuel treatment mapping and the domains are quite extensive and would like to be able to let the user be able to do the following:

Select a category such as:

Biomass

Experimental

When that category is selected only show the available domains for that category:

Biomass

Chipping

Lop and scatter

Masticate

Mobile biomass facility

Pile burn

Truck to biomass facility

Experimental

Assisted migration

Inoculation reduction

Test new vegetation management tools

I'm not sure if this is possible. If so, anyone have some syntax they can share?

Thanks in advance.

Not an AGOL or Field Maps user, but can you just create Subtypes for those categories then particular domains to each subtype/category?

That's a good suggestion. I was just hoping Field Maps had this capability, I don't know Arcade well enough to figure out.

Looking to set up something very similar. Did you come across the solution by any chance?

To answer the other suggestion with the subtypes: You can do it in Field Maps, but some other ESRI Apps won't allow you to work with subtypes, so I am basically just trying to avoid them.

I had a very similar issue and solved it with Decode function. So in your case, you would do something like this:

Decode($feature["fire_fuel_treatment"],
"biomass", ["chipping", "lop and scatter", "masticate", ""],
"experimental", ["assisted migration", "inoculation reduction", "test new vegetation management tools", ""],
, "")

Not 100% sure if it works in Field maps, as I used this script in a different app, but I don't see a reason why it wouldn't.
