Dynamic Combo Box Field

Question

Hello, I have a question about configuring a form in Field Maps in ArcGIS Online. I can't use a calculated expression in a form field (with a combo box type) to populate the code/values of the combo box, correct?

Something like this wouldn't work? Thanks..

var myList = {

code: "1", value: "choice 1",

code: "2", value: "choice 2",

code: "3", value: "choice 3"

}

return myList

This is my use case as well. I want the user to be able to put a point down in a parcel, and bring up a combo box with the 5 nearest street names to make address entry faster / more error-proof.
Because of the fact that the parcel can be bordered by multiple streets, and the point being placed in the parcel indicating the location of something, it wouldn't necessarily be near the street that the address is based on.

Hi Sarah,

What about the ability to create a simple buffer around a point A, gather up any records from Layer B that fall within 500ft, and present their IDs as a drop down within point A...

This can be done relatively simply in Survey123 but is impossible within Field Maps.

Not sure if this completely fits your use case, but there have been some community workarounds for building multiselect lists based on a domain in a separate field: Multiple choice option in Field Maps - Esri Community

However, you would also have to build the domain for the field in question based on your table data.  This can be done in a few different ways, but adds a bit more legwork to the solution.

I hope this helps.
