Add support for multiple value selection in combobox fields in forms

Yannick-Atos — Thu, 05 Mar 2026 10:52:04 GMT

Many data models require storing multiple categorical values for a single attribute. A common example is selecting several applicable categories, tags, or characteristics for a feature.

In the form configuration of ArcGIS Online and the ArcGIS Maps SDK for JavaScript Editor, combobox fields currently support only single-value selection.

However, there are common workflows where users need to select multiple predefined values from the same domain.

Current behavior

Combobox fields allow selecting only one value from a coded value domain.

To represent multiple values, users currently must:

create multiple boolean fields
create related tables
or manually concatenate values in a text field

These approaches have several drawbacks:

more complex data models
reduced usability for editors
increased risk of inconsistent values

Proposed enhancement

Add native support for multi-select combobox fields in ArcGIS forms.

Possible configuration example:

fieldName: hazard_types inputType: combobox multiple: true delimiter: ";"

Behavior:

Users can select multiple values from the coded value domain.
Selected values are stored in a single string field, concatenated with a configurable delimiter.
Existing single-select combobox behavior remains unchanged.

Example stored value:

holes;cracks;graffiti

Benefits

Supports common tagging and classification workflows
Simplifies data models by avoiding additional fields or related tables
Improves editing usability in web and mobile apps
Provides a consistent solution across ArcGIS editing environments
