Product: Oneo Contao
Contao Version: 4.9.24
Browser and version: -


I am preparing new site with Oneo theme, and some users with smaller screens have problem with navigation and mega menu. I tested it using 1024 px wide screen, and in that case, main navigation is placed in two lines, and user can't access to mega menu on the first navigation link.

It will be more clear on video in attachment.

Main logo is also shown in weird way.

Is this possible to fix, or I have to leave it as it is? Unfortunately, bug is found by client, therefore I want to investigate.

    Thank you for submitting your question!

    Adding the following CSS code to files/oneo/css/custom.css should fix this issue:

    @media screen and (max-width: 1680px) {
        .main-navigation > ul > li {
            margin-left: 1em;
    @media screen and (max-width: 1550px) {
        .main-navigation > ul > li {
            margin-left: 0;
    @media screen and (max-width: 1420px) {
        .main-navigation > ul > li {
            margin-left: -1em;
    @media screen and (max-width: 1300px) {
        .main-navigation > ul > li > a,
        .main-navigation > ul > li > strong,
        .main-navigation > ul > li > span {
            font-size: 0.7em;
            line-height: 2.8;
