TabberList allows you to organise your many lists into a cool tabbed display on any page or post. The tabs are javascript-powered and the default skin uses Sean Catchpole’s awesome idTabs.
The plugin is skinnable – you can add custom css and javascript and really make them your own. It also features the ability to mark out new items and to strikethrough old items.
You can limit the categories by using the attribute ‘cat’ and a comma-separated list of the ids of the categories you want to include in the shortcode. e.g.
<pre><code>[tabberlist cat=1] [tabberlist cat=1,2,5] </code></pre>
You can also set a default title for the list in the admin panel and this can be over-ridden using the ‘title’ attribute as follows:
<pre><code>[tabberlist title='Here is a Custom List Title'] [tabberlist cat=1,2,5 title='A title just for these categories'] </code></pre>

This plugin is can be used for petitions, events, or any verified list and as far as I know is unique in WordPress.
Creating a petition/list/signup is as easy as adding a shortcode to a post or page (or CPT). From there additional editors are available to configure easch aspect of the sign up. Everything is completely self hosted and all list members become users of your site (not a third parties).
Available shortcodes:
[lh_signing_form] (enable signatories on any post, page, or custom post type)
Unconfirmed signatories: [lh_signing_unconfirmed_count]
Confirmed signatories: [lh_signing_confirmed_count]
Total signatories: [lh_signing_total_count]
[lh_signing_unconfirmed_list] (unformated list)
[lh_signing_confirmed_list] (unformated list)
You can customise the display of the signing form ([lh_signing_form]) via a number of shortcode arguments more information is available <a href="https://lhero.org/portfolio/lh-signing/" title="Additional Plugin documentation" rel="nofollow ugc">here</a>
