As for the top menu, I already explained what to do but I see that you have not done so yet.
As for the side menu, insert this css in the custom.css file that you find in the template's css directory.
@media (min-width: 992px) {
#Mod120 {
position: sticky !important;
top: 20px;
}
}
If it is not present, create the file yourself, just a notepad text file that you then rename to custom.css
the pat should be
templates/ja-festival/css/custom.css
Let me know if you have problems
