The Transportation Safety Board has mandated that we add a few requirements to our site. Apparently it’s some kind of law that we need to disclose safety concerns. Complete the following tasks to implement an Accordion using the Bootstrap Collapse Plugin so we don’t scare people all at once.

To start off, let’s hide all the content within each panel for when the page loads. Don’t hide the panel titles though – those are the links. What we need to do is start the body of each accordion item as collapsed.
<div id=‘transportationWarning‘ class=‘panel-collapse collapse‘> <div class=‘panel-body‘> <p>Technically, transporting means making a clone of yourself and killing off the other one. If you believe in a soul, you should be aware of this fact before attempting travel using a transporter.</p> </div> </div>
Now all of the panels are collapsed when the page loads! Add a class of in to the body of the "All Systems Operational" panel to make sure it shows when the page loads.
If you‘re curious how this in class works with the Collapse Plugin, read theBootstrap Collapse Plugin Documentation.
<div id=‘systemsOperational‘ class=‘panel-collapse collapse in‘> <div class=‘panel-body‘> <p>All systems are operational</p>
We‘re getting somewhere! The page looks correct when it loads, but our links don‘t do anything yet. Let‘s make the 2nd panel functional first – the "Weather Alert".
Update the "Weather Alert" link to use the Collapse Plugin. You‘ll need to add 2 data attributes to the link to make this work.
<div class=‘panel panel-warning‘> <div class=‘panel-heading‘> <h4 class=‘panel-title‘> <a href=‘#weatherAlert‘ data-toggle="collapse" data-target="#weatherAlert">Weather Alert</a> </h4> </div> <div id=‘weatherAlert‘ class=‘panel-collapse collapse‘> <div class=‘panel-body‘> <p>The National Weather Service has issued a solar flare watch for the following time periods. Please plan accordingly:</p> <ul class=‘list-unstyled‘> <li><strong>February 9th, 21:43</strong></li> <li><strong>May 18, 19:82</strong></li> <li><strong>July 4, 08:42</strong></li> </ul> </div> </div>
Convert the links for "All Systems Operational" and "Transportation Generals Warning: Transporters" to also use the Collapse Plugin.
data-toggle="collapse" data-target="#systemsOperational"
data-toggle="collapse" data-target="#transportationWarning"

Our Accordion Component is using the JavaScript Collapse Plugin, but it’s missing something. Clicking on one link in the accordion should collapse the previously open item. In this case, we only want one panel to be open at any given time. Follow the tasks below to make this happen.
It turns out that using the data-target attribute with the Collapse Plugin manages just a single element. If you want to control multiple elements at once that share the same parent, you can instead use the data-parent attribute passing in a shared parent.
Update the "All Systems Operational" link to use this new attribute targeting the parent Panel Group element (.panel-group).
<a data-toggle=‘collapse‘ data-parent=‘.panel-group‘ href=‘#systemsOperational‘>All Systems Operational</a>
We‘re on the right track, but the other two panels in our accordion component don‘t know to collapse when the other ones are clicked. Go ahead and update the other two links to also point to the same parent.
