jQuery click function converted in hover on full width dropdown menu

I need modifying the jQuery code so when hovering over full width dropdown it opens instead of clicking on it, but when width is less than 798px, the dropdown must stay the way it is now, opened when clicked.
I have been trying to change .click to .hover, but without success. On this state it opens the dropdown menu when hovered, but on mouse out it closes immediately.It would be good for someone to share a solution on this problem, because this is not my code(downloaded free) and I am not well in JavaScript programming.
Thank you,
CP

// Close one dropdown when selecting another

How to make a responsive menu with simple jquery and css

I am trying a simple responsive menu with Css and jQuery. I want the jQuery script to work only on a certain window width. When I resize the browser. Here is my code.
$(document).ready(function(){
$(".resmenu").click(function(){
$(".menu").slideToggle();
});
$(".submenu").click(function(){
$(this).toggleClass("active_submenu");
$(this).parent().find(".dropdown").slideToggle();
});
});

It is working on 768px screen size, but when I click on the drop-down link instead of hover on more than 768 screen size, the drop down link is slide toggle. I need this script work on certain width only.

Use $(window).width() to get the width of the screen and use it in your condition:
if ($(window).width() < 768) {
// run your code here
}
See code snippet:
$(document).ready(function() {
$(".resmenu").click(function() {
$(".menu").slideToggle();
});
$(".submenu").click(function() {
if ($(window).width() < 768) {
$(this).toggleClass("active_submenu");
$(this).parent().find(".dropdown").slideToggle();
}
});
});

In css change "container" width to 100%, and set max-width to 980px.

</nav>
<div class="clear"></div>
</div>
</header>
</div>

At first you have to change for web view bellow css code for left position for nav. Also logo should be remove otherwise logo & menu overlap if you want to logo is left position.
#navigation {
position: absolute;
left: 40px;
bottom: 0px;
}
Also you want to change your menu bar background color then change to this css code
#wrap > header {
background-color: #fff;
}
Note: If you do that you should be change your menu font color like black otherwise your font menu font color & menu background color looking messy.

Sub-menu hover menu issue on css

I want to make a code where I hover my mouse through the menu items, and appears a submenu with a list ...
Here's my html nav code on CSS first and then the HTML code ...:
nav {
background-color: #FFF;
width: 960px;
margin: 0 auto;
}
div.ajuste {
clear: both;
}
nav ul {
width: 95%;
margin: 5px 5px 0 5px;
padding: 10px 10px 10px 6px;
height: 40px;
line-height: 100%;
background: #FFF;
/* position:relative;
z-index:999;
overflow: hidden;*/
float:left;
list-style-type: none;
}
nav li {
margin-bottom: 10px;
padding-right: 25px;
float: left;
/*position: relative;*/
/*list-style: none;*/
}
nav a {
color: #36E;

text-decoration: none;
/*margin-right: 6%;*/
font-family: arial, sans-serif;
font-style: normal;

}
ul.dropdown ul {
visibility: hidden;
position: absolute;
top: 100%;
left: 0;
z-index: 598;
width: 100%;
}
ul.dropdown ul li {
float: none;
}
ul.dropdown ul ul {
top: 1px;
left: 99%;
}
ul.dropdown li:hover > ul {
visibility: visible;
}
<nav>
<ul id="menu_bar" class="dropdown">
<li>Inicio</li>

<ul>
<li>Innerspeaker</li>
<li>Lorenism</li>
<li>Currents</li>
</ul>
</li>
</ul>
<div class="ajuste">
<nav>

nav {
background-color: #FFF;
width: 960px;
margin: 0 auto;
}
div.ajuste {
clear: both;
}
nav ul {
width: 95%;
margin: 5px 5px 0 5px;
padding: 10px 10px 10px 6px;
height: 40px;
line-height: 100%;
background: #FFF;
/* position:relative;
z-index:999;
overflow: hidden;*/
float:left;
list-style-type: none;
}
nav li {
margin-bottom: 10px;
padding-right: 25px;
float: left;
/*position: relative;*/
/*list-style: none;*/
}
nav a {
color: #36E;
font-weight: bold;
text-decoration: none;
/*margin-right: 6%;*/
font-family: arial, sans-serif;
font-style: normal;
font-size: 15px;
text-decoration: none;
display: block;
padding: 6px 20px 6px 20px;
/*margin-bottom: 10px;*/
}
nav a:hover {
color: #0505B4;
}
nav a.active {
color: #1414D3;
}
ul.dropdown, ul.dropdown li, ul.dropdown ul {
list-style: none;
margin: 0;
padding: 0;
}
ul.dropdown {
position: relative;
z-index: 597;
float: left;
}
ul.dropdown li {
float: left;
min-height: 1px;
line-height: 1.3em;
vertical-align: middle;
}
ul.dropdown li.hover, ul.dropdown li:hover {
position: relative;
z-index: 599;
}
ul.dropdown ul {
visibility: hidden;
position: absolute;
top: 100%;
left: 0;
z-index: 598;
width: 100%;
}
ul.dropdown ul li {
float: none;
}
ul.dropdown ul ul {
top: 1px;
left: 99%;
}
ul.dropdown li:hover > ul {
visibility: visible;
}
<nav>
<ul id="menu_bar" class="dropdown">
<li>Inicio</li>
<li>Biografía</li>
<li class="submenu">
Discografía
<ul>
<li>Innerspeaker</li>
<li>Lorenism</li>
<li>Currents</li>
</ul>
</li>
</ul>
<nav>

You have an extra li tag. Get rid of it, and it should work
<nav>
<ul id="menu_bar" class="dropdown">
<li>Inicio
</li>
<li>Biografía
</li>
<li class="submenu">Discografía
<ul>
<li>Innerspeaker
</li>
<li>Lorenism
</li>
<li>Currents
</li>
</ul>
</li>
</ul>
<div class="ajuste">
<nav>

Dropdown always align center

I have to make dropdown always align center, according to the parent tag. Any help would be greatly appreciated.
The example is given below:
Fiddle Link: http://jsfiddle.net/abidkhanweb/ojxpt4m2/

You can do something like this:
#menu {
border-bottom: 1px solid #DDD;
color: #fff;
display: block;
float: right;
height: 18pt;
line-height: 18pt;
list-style-type: none;
text-transform: uppercase;
width: 100%;
font-size:14px;
position:absolute;
}
#menu > li{
background-color: #003399;
border: 1px solid #DDD;
margin-top:-1px;
float: right;
position: relative;
margin-left: 1%;
padding-left: 2%;
padding-right: 2%;
}
#menu li:hover {
opacity: 0.8;
}
#menu li .wrapper .submenu {
display: block;
margin-left: 50%;
width:100%;
}
#menu li .wrapper {
display: block;
position: absolute;
top: 19pt;
right: 50%; /*this will center the div*/
white-space: nowrap;
}
#menu li:hover .wrapper .submenu {
display: block;
}
.submenu li {
display: inline-block;
padding-left: 1.5%;
white-space: nowrap;
opacity: 0.7;
}
.submenu li a {
padding-right: 3%;
padding-left: 3%;
background-color: #000;
display: inline-block;
}
#menu ul {
list-style-type:none;
list-style-image:none;
margin:0px;
padding:0px;
}
#menu li.topmenu {
float:left;
}
.topmenu a {
float:left;
width:110px;
text-align:center;
color:#C37000;
padding:1px 5px;
border-collapse:collapse;
font-weight:bold;
text-decoration:none;
margin:0;
}
.topmenu ul{
display:none;
}
.submenu a{
padding:1px 5px;
border:1px solid #C37000;
border-collapse:collapse;
color:#C37000;
font-weight:bold;
text-decoration:none;
background-color:#7F4800;
margin:0;
width:100%;
}
.submenu a:hover {
color:#4C4C4C;
background-color:#ffddbb !important;
}
.topmenu:hover ul {
display:block;
z-index:500;
}
<ul id="menu">
<li class="topmenu">Menu 1</li>
<li class="topmenu">Menu 2
</li>
<li class="topmenu">Policies
<div class="wrapper">
<ul >
<li class="submenu"><a>Field 1</a></li>
<li class="submenu"><a>Field 2</a></li>
<li class="submenu"><a>Field 3</a></li>
<li class="submenu"><a>Field 4</a></li>
</ul>
</div>
</li>
<li class="topmenu">Menu 4</li>
</ul>

I assume you have applied position: absolute to the dropdown, for you to position it to the left, set the left property to the value of your padding for the policies container like so:
nav {
background: orange;
}
ul {
margin: 0;
padding: 0;
list-style-type: none;
}
nav > ul > li {
position: relative;
top: 0;
left: 0;
margin-left: 50px;
}
nav > ul > li > a {
display: inline-block;
color: white;
text-decoration: none;
padding: 5px 10px;
background: green;
}
nav > ul ul {
background: #eee;
border: 1px solid #000;
padding: 10px;
position: absolute;
left: -10px;
}
<nav>
<ul>
<li>Policies
<ul>
<li>Policy 1</li>
<li>Policy 1</li>
<li>Policy 1</li>
<li>Policy 1</li>
</ul>
</li>
</ul>
</nav>
