<p dir="auto">Bug:<br>
If you click a bit quickly and sequentially group items <a class="issue-link js-issue-link" data-error-text="Failed to load title" data-id="1446398" data-permission-text="Title is private" data-url="https://github.com/twbs/bootstrap/issues/2" data-hovercard-type="issue" data-hovercard-url="/twbs/bootstrap/issues/2/hovercard" href="https://github.com/twbs/bootstrap/issues/2">#2</a> and <a class="issue-link js-issue-link" data-error-text="Failed to load title" data-id="1446658" data-permission-text="Title is private" data-url="https://github.com/twbs/bootstrap/issues/3" data-hovercard-type="pull_request" data-hovercard-url="/twbs/bootstrap/pull/3/hovercard" href="https://github.com/twbs/bootstrap/pull/3">#3</a>, they both open. (should not occur). same thing can happen with any two groups, if cliked a bit more quick than normal speed, while browsing.</p>
<p dir="auto">Feature Request:<br>
Options variable: force one group item to be always visible, so that the user will not hide all groups together on a static layout page.</p>
