Simple widget for creating simple signup forms that drop into a MailChimp list. Original idea and code is based off of this MailChimp-Widget repository. I've since made a bunch of customizations centered around making the plugin more customizable both from the user and development perspective.

Here is a high level overview of the features:

• Multiple widgets on a single page (good for lead pages)
• Defaults to bootstrap classes
• Easy template customization
• Shortcode

• Add templates/mc-widget.php to your theme to customize the widget template. Copy the default template for an easy starting point.
• The shortcode has the following customization options:
  • learn_more - path for learn more button, can be empty
  • description - can be empty
  • before_widget
  • after_widget
  • after_title
  • signup_text
  • collect_last
  • collect_first

You can also setup custom forms. The js-mailchimp-form class will notify the JS library to hook into the submit event on the form.

<form action="/blog/" class='js-mailchimp-form' method="post">
  <input type="hidden" name="ns_mc_number" value="2">
  <div class="input-group">
    <input class="form-control required email" type="email" name="ns_widget_mailchimp_email" placeholder="Email Address" value="" />
    <span class="input-group-btn"><button class="btn btn-primary" id="mc-embedded-subscribe" name="subscribe" type="submit">Subscribe</button></span>
  </div>
</form>

• Use data attributes to trigger MC signup on any forms
• Select different templates in MC widget admin
• Better GROUPINGS merge var handling
• If group type is radio button, it's possible to 'subscribe' two separate times to two groups that were designed to be mutually exclusive
• Leaner JS. Remove spinner & mask dependencies
• Use grunt for JS + CSS minification / workflow
• More code cleanup, move widget admin into template instead of mixing the HTML in with the class code
