safari 2.0 bookmarks

[gary dorn]

In safari 2.0, on my book mark bar, some of my bookmarks are folders, 
some of these folders have either a triangle or square symbol next to 
the name.
when I clicked the square symbol, it opened up a 2nd book mark bar 
row with all the book marks ana preceeded to get each of the 
bookmarks ( 50 + of them).
I've posted an image here

this feature is new to me
how do I stop or disable it.
