<h2>What is it</h2>
<p>A tabs component that provides different sections of content that are displayed one at a time when the user selects that information. </p>
<h2>When to use it</h2>
<p>The tabbed user interface enables users to jump to their target section quickly. Tabs present like logically group information on the same page. Information should </p>
<ul>
<li>be logically chunked and ordered</li>
<li>be arallel in nature</li>
<li>show user's context</li>
<li>obvious where they begin and end </li>
</ul>
<p>Users should not need to see content of multiple tabs simultaneously and the user should be able to easily recognise where they are within the content. </p>
<h2>How to use it</h2>
<p>The structure of the tab set is defined in html. There are two forms supported. Adding a class of <code class="inline">.tab-group</code> to the container element will work in place of the <code class="inline">tabset</code> tag, and the tab panels can be defined using either <code class="inline">tab=""</code> or <code class="inline">data-tab=""</code>. Passing an optional element to the init function will initialise tabs within that element. Adding a <code class="inline">order=""</code> or <code class="inline">data-order=""</code> element to the tabset you can have the tabs sorted in a consistent order across tabsets.</p>
<h2>Example</h2>
<pre class="language-pug" tab="pug">tabset(order="tab2, tab1")
div(tab="tab1")
div(tab="tab2")
</pre>
<tabset id="tabs">
<pre class="language-html" tab="html">
<tabset id="uniqueID" order="tab title 2,tab title 1">
<div tab="[tab title 1]"></div>
<div tab="[tab title 2]"></div>
</tabset></pre>
