Submenu are broken and some submenu are not visible.

Applied MR 3. The broken menu styles are now fixed. The appearance would be further improved by removing the left space in the submenu. Attaching screenshots after the MR for reference.

Patch solves the submenu issue. Moving this to RTBC++

Based on bindu's suggestion, I have added additional CSS to enhance the appearance of the submenus. Please try the following CSS

.uk-navbar-dropdown {
    padding:15px;
}
.uk-navbar-dropdown-nav {
    text-align: left;
    font-size: 15px;
}
.uk-navbar-dropdown-nav > li > a {
    border-bottom: 1px solid #eaeaea;
    padding-bottom: 8px;
}
.uk-navbar-dropdown-nav > li:first-child > a {
    padding-top: 0;
}
.uk-navbar-dropdown-nav > li:last-child > a {
    border: none;
    padding-bottom: 0;
}
.uk-navbar-dropdown-nav > li > a:hover, .uk-navbar-dropdown-nav > li > a:focus {
    color: #e3722e;
}

Please review the attached screenshot showing the results after applying the CSS.
