[Share] How to add a Checkbox to Newsletter Block

If you want to add a checkbox to Newsletter, users need to check it before clicking submit button.

You can follow these.

#1. Find ID of Newsletter Block.

In my example, it is: #block-yui_3_17_2_1_1732180734113_20813

#2. Use this code to Code Injection Footer (or Page Header Injection)

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.7.1/jquery.min.js"></script>
<script>
$(document).ready(function () {
  var newsLetterForm = $(".newsletter-form-body")[0];
    $(newsLetterForm).find("#block-yui_3_17_2_1_1732180734113_20813 .newsletter-form-fields-wrapper").after('<label><input id="checkbox-form" type="checkbox"> I agree as per privacy policy</label>')
  var buttonSubmit = $(newsLetterForm).find("button")
  
  if($(this).is(':checked')){
        buttonSubmit.removeClass("disableButton")
    } else {
        buttonSubmit.addClass("disableButton")
    }
  
  $("#checkbox-form").change(function() {
      if($(this).is(':checked')){
        buttonSubmit.removeClass("disableButton")
    } else {
        buttonSubmit.addClass("disableButton")
    }
    });
});
</script>
<style>
#block-yui_3_17_2_1_1732180734113_20813 .newsletter-form-button.disableButton {
  background-color: gray!important;
  pointer-events: none;
}
#block-yui_3_17_2_1_1732180734113_20813 div.newsletter-form-body {
    display: flex;
    flex-direction: column;
}
</style>
