Drop down into another drop down

IBGemeente_Amsterdam — Mon, 03 Jun 2019 10:36:40 GMT

Hey Esri,

I'm working on a map where people can place points with a comment. I have a few categories that they can choose from in a drop down menu, but would it be possible to make sub categories? So for example a comment about parking. where when placed you are presented by a unique list of options for parking. And when you choose a comment about trafic for example you get a different drop down menu. Is this possible within Arcgis Online?

Kind regards,

Bram van den Berg

Hi IB Gemeente Amsterdam‌,

Yes, this can be done by using subtypes with applied coded domains in your feature service.

Introduction to subtypes—Geodatabases | ArcGIS Desktop

Subtypes are a subset of features in a feature class, or objects in a table, that share the same attributes. They are used as a method to categorize your data.
Subtypes allow you to do the following:
Apply coded (or ranged) domains to the fields of a subtype, enabling you to constrain input information to a valid set of values.

So, in your case, comments about either parking or traffic would be the subtypes, both showing a different range of domain values (subcategories) in a pull down list.

Recently implemented this (for a customer in the Netherlands) and it was exactly what they wanted.

Hope this helps,

Egge-Jan

Thank you for the quick response! So I understand that it is only possible in Arcgis Pro, and then it is possible to host this in Arcgis online and it will keep this functionality?

Hi Bram,

You did not really describe the architecture of your application, but while you mentioned a map in ArcGIS Online, I supposed you have a basemap with a Feature Layer on top of it.

This Feature Layer should contain the subtypes and domains, as explained above.

You can manually prepare or use a Python script to create a Feature Class with subtypes and domains in ArcGIS ArcMap (or ArcGIS Pro, if you wish to) and publish it from there to ArcGIS Online.

(Personally, I have written a Python script to prepare a FGDB with Feature Classes with the relevant functionality, just in case I have to ever implement it again...)

P.S. Als je wilt kun je buiten dit forum om contact opnemen om e.e.a. nader te bespreken.

Cheers,

Egge-Jan

I will contact you outside of the forum in that case, might be easier for the current situation. Is it okay if I send you an email on the address you have on your website?
