Multi Select Combobox

[jaykapalczynski]

I have a project up and trying to outline a few ideas.

I want to add a point and add attribute info.  No Big deal there.

But then I have to try and record that location which contain multiple counties (that location supports multiple counties)

I dont want to create polygons, I would rather stay with the point location, as there might be overlap between the locations supporting the same county.

That being said I was thinking of a related table or a field that will hold an array of some sort...

Where I could:

1. Select the drop down combobox and choose multiple counties and it stores these values in a field in the FC

2. Select the drop down combobox and choose multiple counties and it stores in the related table

I would much rather use option one above.  My question is this possible?  Can I select multiple values in a combobox and write those values to a single field in a FC via AGOL web map?

Or could I select multiple counties in the map and then write those values to a field in the point FC....I actually like this option the best....but I assume I would have to write this in a JS app that I create not via AGOL Editing.
