Forms

Design the form people fill in when they add or edit a feature, on the web or in the Field App, so the data you capture stays consistent.

A form collects a feature's attributes when people add or edit it, on the web or in the Field App. Each attribute becomes a field, such as a text box, dropdown, or photo field. A field survey uses the form to capture data. See Run a field survey.

Set up a form

1. In edit mode, click the layer's ··· menu in the legend and click Edit attributes. For a new layer, the same dialog opens when you create the layer.

2. Click Add attribute and select a type, or select an existing attribute in the list.

3. Adjust the attribute's settings in the Basics, Survey, and Table sections. The Preview on the right shows the form as you go.

4. Drag attributes in the list to set the order of the form's fields.

5. Click Update layer.

Use the Survey and Table sections to hide a field from the form or the table. Hidden fields keep their data. To show a field without allowing edits, turn on Read only in Basics.

Supported attribute types

An attribute's type sets what kind of value its field accepts, and you can't change it after you add the attribute. See Add, rename, or delete attributes.

Type	Holds	Example
Text	Any text	Area 1, Reviewing proposal
Number	Whole or decimal numbers	10, 0.54
Boolean	True or false	true
Date	A date, and optionally a time (turn on Show time)	2027-01-01 16:30
Image	One or more photos or files per feature	A .jpg, .png, .heic, or .pdf file
Person	A member of your workspace, such as the inspector for a site	Nora Smith

To add photos to features, add an Image attribute. People can then attach photos in the feature editor or take them in the Field App. You can also use the attribute as the header image of a popup.

Add a dropdown list

A dropdown (single-select field) offers a fixed list of choices, which keeps values consistent. Text and Number attributes can use one.

1. In the Edit attributes dialog, select the attribute.

2. In the Basics section, set Form type to Single-select.

3. In the Values list, enter each value you want to offer, or paste a list separated by commas or line breaks to add many at once. Each value gets its own row.

To turn a Text or Number attribute that already has values into a dropdown, follow the same steps. When you set Form type to Single-select, the first row of the empty Values list shows how many values are in your data. Click Prefill in that row to build the list from them. For an attribute with many values, the button reads Prefill top and the number of values it adds. The row doesn't appear for a new attribute, or once the list has values.

A dropdown holds one value per feature. To record several choices for one feature, add a Boolean attribute for each choice.

Advanced form settings

Available on the Business and Enterprise plans. Compare plans

Use required fields and show if conditions to control what a form collects. Set them in the Edit attributes dialog.

Make a field required

Select the attribute and turn on Required in Basics. The field then shows an asterisk (*), and the feature can't be saved until the field is filled in. Saving with it empty shows This field is required.

Show if conditions

A show if condition makes a field appear only when another field's answer meets a condition. For example, ask for a damage rating only when Damage observed is true.

1. In the Edit attributes dialog, select the field that should appear conditionally.

2. In the Survey section, next to Show if, click Add condition.

3. Select the field to check, a comparison, and a value.

4. Optional: Add more conditions, and select whether all or any of them must be met.

If a field's show if condition is no longer met, Felt clears its value the next time the feature is saved. Conditions affect only the form; the table and exports show every value.

Metadata fields

Metadata fields are attributes Felt fills in automatically. Add one with Add attribute, like any other attribute. They're read-only and hidden from the form by default; to show one, turn off Hidden in its Survey section.

Measurement fields record each feature's size and update when its geometry changes.

Field	Layer type	Records
Length	Line	The line's length
Perimeter	Polygon	The distance around the polygon
Area	Polygon	The polygon's area

Edit tracking fields

Available on the Business and Enterprise plans. Compare plans

Edit tracking fields record who created or last changed each feature, and when: Created at, Created by, Modified at, and Modified by.

Frequently asked questions

Can a field be calculated or filled in automatically?

No. Apart from metadata fields, Felt doesn't calculate a field from other fields or from the feature's location. To fill in values for many features at once, ask Felt AI or use the Join operation in Spatial analysis.

Can a dropdown's options depend on another field or come from a layer?

No. A dropdown's values are a fixed list you enter or prefill once. To adapt a form to earlier answers, add a field for each case and use show if conditions to show only the one that applies.
