I have created two bootstrap accordions, one below the other. I did not like the way that the panels were awkwardly shifting locations when I had them all as one accordion, so I cr

Solution 1:

To have multiple accordions but only one open at the same time you just need to combine the data-parent. So I have made a codepen for you to see it working.

I just changed all data-parent to data-parent="#accordion,#accordion2"

            <a role="button" data-toggle="collapse" data-parent="#accordion,#accordion2" href="#collapseOne" aria-expanded="false" aria-controls="collapseOne">
                <h2>Bites and Stings</h2>
