The latest ArcGIS Online update brings smarter, more flexible data editing across Map Viewer, Web Editor, and Instant App templates. Highlights include the ability to add fields while building forms, collect richer data with the new multiple choice question type, and manage attachments with greater control. You’ll also find handy new tools like the snap chip and tangent curve segment tool. In this edition of Editor’s Corner, we’ll cover these updates and more. Let’s go.
Enhancements to Forms
First, we’ll explore significant improvements to forms and form builder. Here’s a closer look at the top three improvements:
1. Add New Fields
You can now create new fields directly in the form builder, making it easier to customize forms and capture the information you need. Simply drag a Basic or Choice element from the Form elements pane onto the form canvas, then set properties such as display name, default value, field length, and more. When you save the form, your new fields are automatically added to the layer.
2. Multiple Choice Questions
Multiple choice is a new input type in forms that allows you to select more than one option from a list. For example, if you want to record all invasive species present at a monitoring site, simply check multiple values. Futher tailor editing worklows by setting default values, field length, or requiring a minimum number of selections. Additional features include:
- Select all: Lets editors use a single checkbox to quickly select every option.
- Other: Prompts editors to enter a value not in the list. These entries are stored in a separate field, which you can choose, or have created automatically.
3. New Attachment Element
You’ve been asking for it, and we listened! Forms now support attachment elements, giving you more control over what attachments are added to your data.
When you configure a Form in Field Maps Web Designer or Map Viewer, you will notice a new section for attachment elements. Simply choose between a General, Media, and Document input type (or pick all three) and drag it directly onto the canvas. From here, you can tailor the editing experience for attachments by:
- Adding an associated keyword
- Choosing which of the following file types are accepted: photo, audio, video, and document files
- Enforcing a minimum / maximum file limit
- Leveraging arcade driven expressions to determine the editability & visibility of an attachment element
- Automatically calculating a file name once an attachment is uploaded
Additionally, if you are using the General attachment element, you can decide how to handle pre-exisiting feature attachments. Read more on those settings here.
New Editing Tools
Next, we’ll take a look at new data editing tools across the platform.
Tangent Curve Segment Tool
The Tangent curve segment tool is the the latest edition to our true curve drawing tools. Located on the draw toolbar in apps like Map Viewer, and the editing toolbar in Web Editor, it lets you draw a smooth, curved line tangent to a previous line, great for drawing features like exit ramps flowing off an interstate. To learn how to get started with true curve drawing tools in ArcGIS Online, see this article.
Configure Contingent Values
If you leverage contingent values to define rules for collecting data across multiple fields, this one is for you. Now you can create and update contingent values directly in ArcGIS Online. Those changes carry through when editing using forms or tables across apps like Map Viewer and Web Editor. For a deeper dive, check out this article.
Enhancements in ArcGIS Web Editor
Finally, we’ll highlight some powerful new tools and improvements to ArcGIS Web Editor and the Web Editor Instant App template. Here’s a break down of what’s new.
Snap Chip
If you work with z-values, the new snap chip in ArcGIS Web Editor is a game changer. It shows coincident features and their heights, helping you choose the right one when placing points or vertices. When features share a location but have different z-values, the snap chip appears so you can select exactly which to snap to. To learn more, read the full article here.
Editing Templates
Over the past year, we’ve streamlined the way you manage editing templates in ArcGIS Online. With this update, template descriptions now appear in the Create features pane in Web Editor, making it easier for editors to select the right template when creating features.
Reshape Reimagined
With this update, we worked to make editing features using the Reshape tool more intuitive. Prior to the June 2026 update of ArcGIS Online, reshaping a polygon was shown in a yellow line until the reshape was completed. Now, removed areas will be shown in yellow and appended areas will be shown in blue, giving you a preview of the resulting geometry as you digitize.
New Tooltips for True Curve Tools
When you hover over a true curve drawing tool on the editing toolbar, a new tooltip appears with a short GIF, providing you with a quick visual glance at how to use the tool.
Enhanced Table Editing in Web Editor Template
Earlier this year, the Web editor template landed in the Instant Apps gallery, letting you build custom web editing apps in minutes. The latest update brings more data editing tools to the table, quite literally, including the calculate field experience and a button to quickly get started creating a new feature or record.
Wrap up
With this update, we’ve introduced several new features to help streamline data editing. You’ll find new tools across apps like Map Viewer, Web Editor, and Instant App templates from multiple choice questions and contingent values to more flexible attachments. We hope these tools will help you get the job down. Don’t forget to share your ideas and feedback with us over on Esri Community, and be sure to join us at the Esri UC 2026 this July to dive deeper into editing in ArcGIS Online.
