Field Object

Field objects are the primary mechanism for accessing and manipulating field data and properties. They can be accessed via the Context API.

Field Property	Type	Description
value	optional polymorphic: boolean | string | string[] | number | number[] | Promise | Promise[] | Record<string, any>	Read/write property for getting or setting the field value. The type of the value varies depending upon the field type. The value is an array type for multi-valued field types (e.g. multi select, etc.) or if the field is repeating. null if no submission, Promise<File> if file submission, Base64 string if signature.
type	string enum	The field type (e.g. textarea, checkbox, etc.). Only available for fields on the loaded form. Read-only property.
displayText	optional string	The text to display to your user along with the field Read-only property.
onThisForm	boolean	True if this field appears on the loaded form. False if the field is from another form. Read-only property.
isHiddenField	boolean	True if this field is one of the special 'hidden' fields that do not appear on a form. False if this field is a regular form field. Read-only property.
placeholder	string	The placeholder text for the field that is shown when the field has no value. Read/write property.
disabled	boolean	If the field is disabled or interactable. Read/write property.
options	string[] | { value: string; label ?: string; image ?: string }[]	Allowed options to choose from, if the field specifies them (e.g. dropdown, radio buttons, etc.). Read/write property.
setStyles()	(styles: Record<string, any>) => void	Dynamically update the styles of a form field. Style API Reference
setError()	(...error: string | {index:number; message: string}) => void	Method used to set the error of a field. The error may be passed as text or as an object. An error with the shape {message: <fieldErrorString>, index: <fieldIndex>}} will set an error for a specific repeatable field across its repetitions. Setting an error prevents the step from submitting.
equals()	(...values: string | Field) => boolean	Returns true if the field equals any of the values passed. A value may be a string or another Field.
notEquals()	(...values: string | Field) => boolean	Returns true if the field does not equal any of the values passed. A value may be a string or another Field.
greaterThan()	(...values: string | Field) => boolean	Returns true if the field is greater than any of the values passed. A value may be a string or another Field.
greaterThanOrEqual()	(...values: string | Field) => boolean	Returns true if the field is greater than or equal to any of the values passed. A value may be a string or another Field.
lessThan()	(...values: string | Field) => boolean	Returns true if the field is less than any of the values passed. A value may be a string or another Field.
lessThanOrEqual()	(...values: string | Field) => boolean	Returns true if the field is less than or equal to any of the values passed. A value may be a string or another Field.
isFilled()	() => boolean	Returns true if the field contains a value that was set by the user or by logic.
isEmpty()	() => boolean	Returns true if the field does not contains a value, i.e. the field was not set by the user or by logic.
isTrue()	() => boolean	Returns true if the field is true or truthy.
isFalse()	() => boolean	Returns true if the field is true or falsy.
contains()	(...values: string | Field) => boolean	Returns true if the field text contains the text of any of the values passed. The text must match on upper/lower case exactly. A value may be a string or another Field.
doesNotContain()	(...values: string | Field) => boolean	Returns true if the field text does not contain the text of any of the values passed. The text must match on upper/lower case exactly. A value may be a string or another Field.
containsIgnoreCase()	(...values: string | Field) => boolean	Returns true if the field text contains the text of any of the values passed. The text comparison ignores upper/lower case differences and will match on different cases. A value may be a string or another Field.
doesNotContainIgnoreCase()	(...values: string | Field) => boolean	Returns true if the field text does not contain the text of any of the values passed. The text comparison ignores upper/lower case differences and will match on different cases. A value may be a string or another Field.
startsWith()	(...values: string | Field) => boolean	Returns true if the field text starts with the text of any of the values passed. The text must match on upper/lower case exactly. A value may be a string or another Field.
doesNotStartWith()	(...values: string | Field) => boolean	Returns true if the field text does not start with the text of any of the values passed. The text must match on upper/lower case exactly. A value may be a string or another Field.
endsWith()	(...values: string | Field) => boolean	Returns true if the field text ends with the text of any of the values passed. The text must match on upper/lower case exactly. A value may be a string or another Field.
doesNotEndWith()	(...values: string | Field) => boolean	Returns true if the field text does not end with the text of any of the values passed. The text must match on upper/lower case exactly. A value may be a string or another Field.
isNumerical()	() => boolean	Returns true if the field value is a number.
isText()	() => boolean	Returns true if the field value is text and not a number.
selectionsInclude()	(...values: string | Field) => boolean	Used for multi-valued fields. Returns true if any of the field's values exactly equal the text of any of the values passed as parameters. A value may be a string or another Field.
selectionsDoNotInclude()	(...values: string | Field) => boolean	Used for multi-valued fields. Returns true if none of the field's values exactly equal the text of any of the values passed as parameters. A value may be a string or another Field.
