To setup a class toggle, start by adding the attribute data-toggler to an element. The value of data-toggler is the class you want to toggle (like .classname and classname). Also give the element a unique ID so it can be targeted.
<ul class="menu" id="menuBar" data-toggler=".expanded">
<li><a href="#">One</a></li>
<li><a href="#">Two</a></li>
<li><a href="#">Three</a></li>
<li><a href="#">Four</a></li>
</ul>
Then, add data-toggle to any element, with the ID of the target as the value of the attribute. Now, any time you click on this element, the class will toggle on and off on the target.
<p><a data-toggle="menuBar">Expand!</a></p>
Instead of toggling a class, you can also toggle visibility. When toggled, the element comes into or out of view using a Motion UI class.
Instead of data-toggler, add the attribute data-animate. The value of the attribute is the in animation you want, followed by the out animation.
<p><a data-toggle="panel">Toggle Panel</a></p>
<div class="callout" id="panel" data-toggler data-animate="hinge-in-from-top spin-out">
<h4>Hello!</h4>
<p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Dicta quas optio alias voluptas nobis iusto mollitia asperiores incidunt reprehenderit doloribus voluptatibus officiis minus, inventore, quasi nisi. Consequuntur, quidem. Sint, dicta?</p>
</div>
To create an element that can be closed once, add the attribute data-closable. Then add a click trigger inside the element using data-close.
<div class="callout" data-closable>
<button class="close-button" data-close>×</button>
<p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Labore praesentium sint alias dolorum qui vel quaerat, libero consequatur non esse asperiores veritatis commodi, odit eum ipsam nemo dicta iste aliquam.</p>
</div>
data-closable can be configured with a custom exit animation.
<div class="callout" data-closable="slide-out-right">
<button class="close-button" data-close>×</button>
<p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Labore praesentium sint alias dolorum qui vel quaerat, libero consequatur non esse asperiores veritatis commodi, odit eum ipsam nemo dicta iste aliquam.</p>
</div>
The data-toggle attribute only toggles classes/visibility on click. You can also have the toggle fire when an element is focused or unfocused using data-toggle-focus.
<input type="text" data-toggle-focus="form-callout" placeholder="Click in here to reveal extra content">
<div class="secondary callout is-hidden" id="form-callout" data-toggler="is-hidden">
<p>This is only visible when the above field has focus.</p>
</div>
The data-toggle, data-close, and data-open attributes can now target multiple elements! The syntax is simple; just pass a space separated list to the data-x attribute like so:
<button class="button" data-toggle="foo bar baz">Toggle things</button>
Then the elements with ids of foo, bar, and baz will be toggled any time your button, (or any other element you choose), is clicked.
