Overview of Gravity Forms Auto List Field
Gravity Forms Auto List Field is a premium Gravity Perks add-on that automatically syncs the number of rows in a Gravity Forms List field with a Number, Quantity or Product field. Instead of asking users to manually add and remove rows, this smart automation keeps your List fields perfectly in step with quantities, tickets, shifts and other numeric inputs, while also letting you capture the row count for calculations and reporting.
What does Gravity Forms Auto List Field do?
Gravity Forms Auto List Field adds two core superpowers to standard List fields:
- Automatically add or remove List rows based on another field’s value
- Count the number of List rows and use that count in calculated fields
This makes it ideal for any form where a quantity should equal a number of detailed rows—such as attendees, line items, volunteers, or custom entries.
Key Features of Gravity Forms Auto List Field
Sync List field rows to a field value
Connect a List field to a trigger field so rows update in real time:
- Use a Number, Quantity, Single Product or Calculated Product field as the trigger
- Automatically add rows when the trigger value increases
- Automatically remove rows when the trigger value decreases
- Keep List fields visually aligned with the quantity the user chooses
For example, if a user buys 3 tickets, the List field can instantly show 3 attendee rows—no extra clicks required.
Count List field rows for calculations
Beyond row syncing, you can also count how many rows are in a List field and reuse that value:
- Capture the row count in a Number or Quantity field
- Use a special
:countmodifier in merge tags to reference the row total - Include the row count in calculations, such as totals, fees or capacity counters
This is perfect for:
- Charging fees based on the number of entries
- Tracking how many items or people were submitted
- Driving conditional logic that depends on how many rows were added
Better UX and cleaner data
By controlling List rows automatically, Gravity Forms Auto List Field improves both user experience and data quality:
- Users don’t have to hunt for “add row” buttons or guess how many rows they should add
- Every row is clearly tied to a specific quantity, reducing mistakes and missing information
- The number of rows submitted always matches the trigger field, giving you consistent form data
The result is smoother forms for your users and more reliable entries for you.
Secure, validated row counts
Data integrity is built in:
- When List rows are auto-added, the add-on ensures the number of submitted rows matches the trigger value
- When you use the row count in a calculation, Gravity Forms recalculates on submission to prevent tampering
- Calculated totals that depend on row counts stay trustworthy, even if users try to modify the form data in the browser
This makes Gravity Forms Auto List Field suitable for business-critical forms where accuracy matters.
Practical Use Cases
You can use Gravity Forms Auto List Field in a wide range of real-world scenarios, including:
- Ticket purchase forms
- Generate one attendee row per ticket purchased
- Collect names, meal choices, and contact details for every attendee automatically
- Order and quote forms
- Match a product quantity to a list of line items or custom configuration options
- Capture per-item details such as descriptions, SKUs or notes
- Volunteer and scheduling forms
- Add a row for each shift or time slot a volunteer wants to work
- Collect details for each shift without manual row management
- Registrations, signups and rosters
- Build rosters where each List row represents a participant, team member or child
- Keep the roster size in sync with a chosen number of participants
Any process that pairs a numeric quantity with a list of details can be automated with this perk.
Integrations, snippets and developer hooks
As part of the Gravity Perks suite, Gravity Forms Auto List Field integrates naturally into a broader Gravity Forms workflow:
- Enabled from the Perks tab on List fields inside the Gravity Forms editor
- Works alongside other perks such as Copy Cat, which can copy list counts into other fields
- Offers documented snippets to:
- Count only non-blank rows
- Use dynamic row labels
- Adjust how List field selects behave
For developers and advanced implementers, dedicated hooks allow you to:
- Control whether add/remove buttons are hidden when Auto List is active
- Adjust which field types are allowed as triggers
- Modify initialization options for the front-end script
This makes the perk both user-friendly and highly extensible.
