Hi! I have a client who wanted a custom newsletter that asks for "your name" (this normally says "first name") "your dog's name" (which normally says "your last name") and then your email. I was able to create this using the code below. However, now she wants the "your dog's name" input to be optional, right now it is required - I assume because not everyone has a dog. Can you help me figure out how to do this? 

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.7.0/jquery.min.js"></script>
<script>
 jQuery(document).ready(function($){
  $('div#block-yui_3_17_2_1_1721835085797_5040 .name input').attr("placeholder","Your Name");
})
</script>

<script>
 jQuery(document).ready(function($){
  $('div#block-yui_3_17_2_1_1721835085797_5040 .last-name input').attr("placeholder","Your Dog's Name");
})
</script>

When I test the form I can submit without putting either name field in.

@Ziggy hmm - weird! For some reason that's not the case, at least from my computer or my client's computer. Attached is the message I get.

It was me submitting the test@test.com email address, did that get added correctly?
