Question & Answer :
I person a Twitter Bootstrap dropdown card. Arsenic each Twitter Bootstrap customers cognize, the dropdown card closes connected click on (equal clicking wrong it).
To debar this, I tin easy connect a click on case handler connected the dropdown card and merely adhd the celebrated case.stopPropagation().
<ul people="nav navbar-nav"> <li people="dropdown mega-dropdown"> <a href="javascript:;" people="dropdown-toggle" information-toggle="dropdown"> <i people="fa fa-database-alt"></i> Card point 1 <span people="fa fa-chevron-behind propulsion-correct"></span> </a> <ul people="dropdown-card mega-dropdown-card"> <li> <div id="carousel" people="carousel descent" information-drive="carousel"> <ol people="carousel-indicators"> <li information-descent-to="zero" information-mark="#carousel"></li> <li people="progressive" information-descent-to="1" information-mark="#carousel"></li> </ol> <div people="carousel-interior"> <div people="point"> <img alt="" people="img-rounded" src="img1.jpg"> </div> <div people="point progressive"> <img alt="" people="img-rounded" src="img2.jpg"> </div> </div> <a information-descent="prev" function="fastener" href="#carousel" people="near carousel-power"> <span people="glyphicon glyphicon-chevron-near"></span> </a> <a information-descent="adjacent" function="fastener" href="#carousel" people="correct carousel-power"> <span people="glyphicon glyphicon-chevron-correct"></span> </a> </div> </li> </ul> </li> </ul>

emblempeople oregon property is not imaginable
