Hover do menu continue selecionada enquanto navego pelo submenu

Olá, sou novo tanto no fórum quanto no desenvolvimento de sites e estou com uma dúvida que talvez seja simples de solucionar.

Preciso fazer com que o hover do menu permaneça selecionado enquanto o mouse está na ul do submenu.

Segue o código:

<nav>
	<ul class="menu">
 <li class="active"><a class="active" href="#">EMPRESA</a>
 <ul class="submenu">
 <li><a class="selection" href="#">RESUMO</a></li>
 <li><a href="#">VENDAS</a></li>
 <li><a href="#">COMPRAS</a></li>
 <li><a href="#">ORÇAMENTO</a></li>
 <li><a href="#">RELATÓRIOS</a></li>
 </ul>
 </li>
 </ul>
</nav>

css:

.menu{
	margin: 0;
	padding: 0;
	list-style: none;
	width: 980px;
	margin: auto;
	position: relative;
	z-index: 1;
}

.menu li {

	float: left;
	margin-left: 2px;
}

.menu li a{

	display: inline-block;
	padding: 6px 20px;
	color: #FFF;
	text-decoration: none;
	font-size: 13px;
	font-weight: 500;
	background-color: #23A4CE;
	-webkit-border-top-left-radius: 2px;
 -webkit-border-top-right-radius: 2px;
 -moz-border-radius-topleft: 2px;
 -moz-border-radius-topright: 2px;
 border-top-left-radius: 2px;
 border-top-right-radius: 2px;
 border: 1px solid #23A4CE;
 border-bottom: none;
}

.menu li a:hover, .menu li a.active {

	background-color: #E2E7EA;
	color: #222;
	border: 1px solid #c4c4c4;
	border-bottom: none;
}

.menu li:hover ul, .menu li.active ul{

	display: block;
}

.menu li a.cap {

	background-color: #222;
	border: 1px solid #222;
	border-bottom: none;
}

.menu li a.cap:hover {

	background-color: #E2E7EA;
	color: #222;
	border: 1px solid #c4c4c4;
	border-bottom: none;

}

.submenu{
	list-style: none;
	position: absolute;
	float: left;
	background-color: #E2E7EA;
	width: 1022px;
	;
	display: none;
	padding-left: 30px;
}

.submenu li{

	float: left;
	margin: 0;
}

.submenu li a{

	background-color: transparent;
	border: none;
	color: #7F888A;
	padding: 9px 15px;
	font-size: 11px;
}

.submenu li a:hover{

	border: none;
}

.menu li:hover ul, .menu li.over ul{

	display: block;
}

.submenu li a.selection{

	color: #23A4CE;
}
