Scrollbar zmizne pri použití modálu na Bootstrap - css, twitter-bootstrap, twitter-bootstrap-3, bootstrap-modal

Tak som sa snažil dať modal na odkaz <li> v mojom menu, ale keď naň kliknem, posuvník stránky zmizne.

Pozrite, toto je moja ponuka:

<nav class="navbar navbar-default bg-primary">
<ul class="nav navbar-nav navbar-right">
<li ><a href="#myModal" role="button" data-toggle="modal">History</a></li>
<!-- Modal -->
<div class="modal fade" role="dialog" id="myModal" tabindex="-1" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
<h4 class="modal-title fontblue" id="myModalLabel"> Project</h4>
</div>
<div class="modal-body">
<p class="line">
This page is... x x x
</p>
</div>
</div>
</div>
</div>
</ul>
</nav>

Volám "js" v mnohých formách

<!-- jQuery (necessary for Bootstrap"s JavaScript plugins) -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
<!-- Include all compiled plugins (below), or include individual files as needed -->
<script src="js/bootstrap.min.js"></script>

<!-- Latest compiled and minified JavaScript -->
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/js/bootstrap.min.js"></script>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.min.js"></script>

pozrite sa na rozdiel v posuvníku.

odpovede:

pridať

divName.modal-open {
overflow: scroll;
}

to bude fungovať vo v3 bootstrap
