Many pc and laptops have lower analysis as 1366x768 (this is very usual)
The site is not seemed good as magemenu is not all shown and many things inside the mega menu are hidden?
How we can get over this?

Kindly Check the analysis 1366x768 and see the difference

Dear zakgr

Please go to /templates/sj_revo/css/template-red.css and find:

#meganavigator li.level1 {
float: none;
display: inline-block;
position: relative;
padding: 0;
margin: 0;
list-style: none;
}
=> change to:

#meganavigator li.level1 {
float: none;
display: inline-block;
/* position: relative; */
padding: 0;
margin: 0;
list-style: none;
}
#meganavigator .mega-content{
left:0px !important;
}

Thanks
