 * Disable checkbox until terms of service has been read
 * @link
function wpf_dev_tos_confirmation( ) {
<script type="text/javascript">
jQuery(document).ready( function() { 
	// Set an attribute on the checkbox description to readonly
	jQuery( "div#wpforms-3658-field_14-description" ).attr( "readonly","readonly" );
	// Set an attribute on the checkbox description to overflow-y scroll to check the scroll position
	jQuery( "div#wpforms-3658-field_14-description" ).attr( "overflow-y","scroll" );
	// Set an attribute on the checkbox field to disabled
	jQuery( "#wpforms-3658-field_14 input" ).attr( "disabled","true" );
	// As the user scrolls through the description, envoke this function
	jQuery( "div#wpforms-3658-field_14-description" ).scroll(function () {

		// Evaluate the scroll position inside the checkbox description 
		if (jQuery(this).scrollTop() == jQuery(this)[0].scrollHeight - jQuery(this).innerHeight() || jQuery(this).scrollTop() + jQuery(this).innerHeight() >= jQuery(this)[0].scrollHeight ) {

			// When user has scrolled to the bottom of the description, remove the disabled attribute
			jQuery( "#wpforms-3658-field_14 input" ).removeAttr( "disabled" );


add_action( 'wpforms_wp_footer_end', 'wpf_dev_tos_confirmation', 30 );

This snippet will look at the description of the Checkbox field using the div#wpforms-3658-field_14-description. Our form ID is 3658 and our field ID for the Checkbox field is 14. It will then set two attributes on this field: readonly and overflow-y, scroll. We do this so we can calculate the scroll position of the description so we’ll know when our visitors scroll to the bottom of our disclaimer.

The next section of the snippet will add an attribute of disabled of the Checkbox field using the field ID of #wpforms-3658-field_14 input.

As the user scrolls down through the disclaimer, we’re going to calculate the position of the scroll, when it reaches 0, that’s when we’ll remove the disabled attribute and our visitors can then click the Checkbox to agree.

You’ll need to update these IDs to match your own ID numbers. If you need assistance in finding your ID numbers, please checkout this article.

As your visitors view your form, they won’t be able to agree to your disclaimer checkbox until they have scrolled to the bottom of the disclaimer.
