name
string
A unique name for your form field that you'll use to identify the user's response.*
params
object
These parameters are common to all form fields:
question (required)
string
The main question or label of the form field.
required
true (boolean)
When set, the field becomes required.
description
string
Any extra information that the user may need to fill out the form. Appears right below the question.
fieldSize
"sm"
When set to "sm", the font sizes of the question, description, and answer are made smaller.
labelStyle
"classic"
When set to "classic", the question and description of the form field are made smaller.
subfield
true (boolean)
When set, the question and description of the form field are made smaller. Functionally the same as setting labelStyle to "classic".
disabled
true (boolean)
When set, the input is disabled.
autofocus
true (boolean)
When set, the input will be automatically focused when the parent slide becomes active, or immediately after page load.
id
string
The id attribute of the form field container.
classNames
string[]
attrs
Array<{ name: string, value: string }>
Other HTML attributes of the form field. Each attribute has a name and value property.
displayCondition
{ dependencies: string[], condition: string }
choices (required)
Array<string | { label: string, value?: string }>
Array of choices that can be either strings (e.g., ["Choice 1", "Choice 2"]) or objects with a label for display text and an optional value (e.g., [{ label: "Choice 1", value: "c1" }]). When using objects, if value is not provided, label is used as the value.
multiple
true (boolean)
Allow multiple selections.
horizontal
true (boolean)
Display choices horizontally.
hideFormText
true (boolean)
For multiple selections, when set, the form text "Choose as many as you like" is hidden.
checked
string[]
Array of pre-checked choice values.
Value-label pairs allow different values to be stored than what's shown to users. The label appears for users to select, while the value is stored in the form data. This pattern is particularly useful for storing concise identifiers in a database while displaying more descriptive text in the interface.
Please note, for checked to work with value-label pairs, it must contain the value, not the label.
