Uncaught TypeError: $(...).slideToggle is not a function

Uncaught TypeError: $(...).slideToggle is not a function at toggle ((index):226) at HTMLAnchorElement.onclick ((index):239)

I noticed this one today when looking up this post:!

I think this is caused by the slim version of javascript, i wondered what they had removed, i guess it was that.  

If you get this error you might have to include the full version of jquery rather than the slim one.
