Hi @tomaspernek,
Thank you for reaching out to us.
- This can be possible with custom development or modifying the plugin’s core files but this would be out of the scope of our support. However you can try out the following CSS but this won’t function properly as there is no easy way to handle this:
#sfm-sidebar.sfm-vertical-nav .sfm-has-child-menu .sfm-sm-indicator {
display: none;
}
#sfm-sidebar .sfm-has-child-menu > .sfm-child-menu {
display: block !important;
}
- To change the sub menu styling, try adding the following code in the Theme Options > CSS:
.sfm-nav .sfm-child-menu {
background: #464444 !important;
}
.sfm-nav .sfm-child-menu li a {
font-size: 13px !important;
}
