Link field

Use link_input when you want a respondent to provide a URL. The submitted answer is stored as a string under the field’s name.

Configuration

The table lists properties specific to link_input. For shared field properties such as required, see shared properties.

Name	Type	Required	Default	Description
`placeholder`	string	No	`https://example.com`	Hint text inside the empty input. Supports `{{field}}` piping.
`defaultValue`	string	No	None	Prefills the input. May contain a `{{hidden_name}}` reference.
`validateUrl`	boolean	No	`true`	When `true`, an answer that is not a web address blocks the page.

A web address is accepted with or without http:// or https://.

Validation

A required link field with no answer blocks the page. If URL validation is enabled, an answer that is not a web address—for example, one with no domain ending—also blocks the page. Set validateUrl to false to skip that check.

Submission value

The answer is a string. For a field named portfolio_url, the submission data includes a portfolio_url key whose value is the respondent’s URL.

Example
