Now that BS4 comes with the 'slim' version of jquery, has anyone got a solution to the load problem?

I'm trying create a menu to to load pages into a div, but I can only get it to work by loading an older copy of jquery after the new, slim one.

My code is:


where $MN is the div where I want the particular menu item/page to appear.

This works - up to now, but really isn't a very good solution.

I can find no guidance on how else to replace the original load code.

Any help would be appreciated.
