I had seen a number of users trying to find a simple work around for removing the jump to menu and next/previous activity from course pages for various reasons. Upon trying several changes in course/development/theme settings, I was unsuccessful until finding a solution by mending the CSS itself.
For any users attempting to alter CSS styles within their themes go to:
---- Site Admin -> Appearance -> Themes -> (Select Active Theme) -> Advanced Tab
The RAW CSS text box allows a user to modify CSS tags and change attributes. Usually, inspecting the source on the current page will show the ID that needs changed and using a #select will update changes to the CSS style.
Removing the jump to menu and also prev/next link ended up working as such (though I'm sure it can be cleaned up):
select#jump-to-activity.custom-select {
display: none;
}
select#next-activity-link {
display: none;
}
select#next-activity-link.btn.btn-link {
display: none;
}
a#next-activity-link.btn.btn-link {
display: none;
}
select#prev-activity-link {
display: none;
}
a#prev-activity-link {
display: none;
}
select#prev-activity-link.btn.btn-link {
display: none;
}
a#prev-activity-link.btn.btn-link {
display: none;
}
