Setting to get the menu to not follow on pages

Ive been trying to find where the setting is to get the menu to stay static and in place when viewing pages. Instead its currently floating at the top of the screen a bit transparent if I scroll far enough down to get the first menu out of view. Im sure its a simple section somewhere but ive spent hours looking.

Did I miss it or is it not possible?

There isn’t an option for this in the theme but you just need to add this to a custom CSS plugin:

.stuck {
   position: relative;
