You can add a hyperlink to a checkbox's label text, for example to link "I agree to the Terms and Conditions" to your terms page. There are two ways to do it, depending on whether you need the submitted value to stay clean.
Option 1: Add the link directly in Checkbox Choices
Open the checkbox field's settings and paste a standard link into the Checkbox Choices field:
<a href="https://example.com/terms" target="_blank">Terms and Conditions</a>
This is the quickest method, but note that the full field value, including the link markup, is what gets submitted and stored, rather than a plain "consent given" value. Keep that in mind when reviewing or exporting form submissions.
Option 2: Hide the label and add a separate text element
If you'd rather keep the submitted value simple, hide the checkbox's built-in label, then drag a new text element from the left-hand panel into its place. You can style and link that text element like any other text on the page, including adding a hyperlink to your terms.
This approach keeps the checkbox's submitted value as a plain yes/no, since the link lives in a separate element rather than inside the field itself.
