I have a main menu at the top. For some it reaches to level 3. On my browser it works fine as long as the resolution of the window is maximised. When minimising the screen (results in having a hamburger menu) I cannot reach the level 3 menu.
You can access the website www.volantisconsulting.be, minimise your screen so the hamburger menu appears and then you can try to reach to this page: Les > Tarieven > Winterlessen
I found a thread about it where they said to add the next CSS…
@media (max-width: 991px){
.menu ul.dropdown-menu li a {
width: 90%;
}
.main-navigation ul ul li:hover > ul, .main-navigation ul ul li.focus > ul{
left: 0;
position: relative;
}
}
This worked for me but without the snippet I do have this issue on my iPhone and just on my mac book air (Safari)
