Hello,
Thank you for your question.
Try to add the following code snippet to the Custom CSS area in Theme Settings to change the menu colors.
.mobile-nav,
.mobile-nav .sub-menu-dropdown ul {
background-color:white;
}
.mobile-nav ul li a {
color:black;
}
.mobile-nav ul li a:hover {
color:black;
}
.mobile-nav .icon-sub-menu {
height:50px;
}
.mobile-nav .icon-sub-menu:after,
.mobile-nav .icon-sub-menu:before {
background-color:black;
}
.mobile-nav .sub-menu-dropdown ul:before {
content:none;
}
.mobile-nav .searchform {
border-bottom: 2px solid rgba(180, 180, 180, 0.43);
}
.mobile-nav .searchform input[type=text] {
border: 1px solid rgba(129,129,129,.25);
color:black;
}
.mobile-nav .searchform ::-webkit-input-placeholder {color:rgba(0,0,0,0.6)}
.mobile-nav .searchform ::-moz-placeholder {color:rgba(0,0,0,0.6)}/* Firefox 19+ */
.mobile-nav .searchform :-moz-placeholder {color:rgba(0,0,0,0.6)}/* Firefox 18- */
.mobile-nav .searchform :-ms-input-placeholder {color:rgba(0,0,0,0.6)}
.mobile-nav .searchform button {
color:black;
}
