Field types

How it works

A field's type sets how it looks, what customers can enter and the built-in validation it gets. To add a field, see Build a form.

Use these for basic customer information. They support validation such as required values, length limits and number ranges.

Field	Best for
Text	Names, company details, references.
Email	Contact email addresses.
Long text	Longer notes or requests.
Number	Quantities, values or other numbers.
Phone	Phone numbers with country codes.
Password	Secure login or gated forms.
URL	Website addresses or other links.

Use these for dates and times, such as delivery dates. When you configure the field, you can set the allowed range and availability.

Use these when customers choose from set options. Type the options yourself, or pull them from a data source with data references.

Field	What it does
Select	A dropdown with one choice.
Multiple choice	Choose several options from a list.
Radio	One choice, with the options shown inline.
Toggle	An on/off switch, for example to confirm something.
Checkbox	An on/off choice shown as a checkbox.
Slider	A numeric range.
Country	One country.

Use these for richer information.

Field	Best for
Rating	Feedback or scoring.
Signature	Agreements or approvals.
File Upload	Documents, images and other attachments, such as a resale certificate. You can open them from the entry.
Hidden	Values customers don't see, such as tracking or integration data used by automations.
Tax Information	Tax details such as a VAT number or tax ID.
Workflow trigger button	A button that runs a workflow. Mostly used on internal fields rather than the customer-facing form.

For developers: uploaded files

A File Upload answer is stored as a SparkLayer file ID. Use the Files API to turn it into a download link.

These fields create several sub-fields for you. That keeps answers consistent, especially for B2B account requests and onboarding.

Field	What it includes
Name	Title, first name, last name.
Address	Street, city, postcode, country.

Use these to organise the form.

Field	What it does
Group	Keeps related fields together and lets you apply display logic to all of them at once.
Group with Repeatable on	Lets customers add the same set of fields more than once, for example one row per line item.

See Group related fields for how groups work.

These fields don't collect answers. Use them to guide customers through the form.
