Oh, no!
Another problem with this. Now the active link is not visible at secondary menu.
see here: http://bit.ly/2yrHR5e
I use this custom CSS that before works:
.sidebar .secondary-navigation .main-nav .current-menu-item > .sub-menu,
.sidebar .secondary-navigation .main-nav .current-menu-ancestor > .sub-menu {
opacity: 1;
left: auto;
right: auto !important;
position: relative;
width: 100%;
clear: both !important;
top: auto;
float: none;
visibility: visible;
pointer-events: auto;
}
