filtro de busca num menu dropdown

[ndias 2]

To fazendo um filtro de busca num menu vertical e quero quando clicar abrir um input search para eu digitar alguma coisa. Acontece que quando eu clico ele abre beleza, mas ao colocar o cursor do mouse dentro da input, ele fecha o menu.

 

Alguém poderia me ajudar?

 

Segue o código:

 

HTML

                    <nav class="navbar navbar-default sidebar" role="navigation">
                        <div class="container-fluid">
                            <div class="navbar-header">
                                <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#bs-sidebar-navbar-collapse-1"> <span class="sr-only">Toggle navigation</span> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span> </button>
                               <a class="navbar-brand" href="#">Busca</a>
                            </div>
                            <div class="collapse navbar-collapse" id="bs-sidebar-navbar-collapse-1">
                                <ul class="nav navbar-nav">
                                    <li class="dropdown">
                                        <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false"> Qualquer Coisa <span class="caret"></span> </a>
                                        <ul class="dropdown-menu s11">
                                            <li style="padding: 0 10px;">
                                            <input type="search" class="form-control sh" placeholder="digite qualquer coisa" data-search="s11">
                                            </li>
                                        </ul>
                                    </li>
                                </ul>
                            </div>
                        </div>
                    </nav>
