No clue how to pull off this. Apologies whether it's a stupid question (most likely is!)...

I am likely to give a e-newsletter connect to the home page. I would like this tag to trigger a MailChimp e-newsletter register form which will open on a single page. I'm not going customers to become rerouted to a different page to register. I have were built with a browse around but aren't able to find something that gives me this style.

Any help could be appreciated. Really stumped on that one.

Using jQuery that you can do something similar to this

<span id="newsletter">Sign Up For My Newsletter</span>
<div id="signUpForm" style="display:none;">
    Mail Chimp Code Goes Here <span id="closeSignupForm" style="color: red;">X</span>
</div>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type="text/javascript">
    $('#newsletter').click(function() {
        $('#signUpForm').show();
    })
    $('#closeSignupForm').click(function() {
        $('#signUpForm').hide();
    })
</script>
