Cool attitude for example (8)
I believe the answer is:
instance
'example' is the definition.
(synonyms)
'cool attitude' is the wordplay.
'cool' becomes 'in' ('in' can mean fashionable or cool).
'attitude' becomes 'stance' (stance is a kind of attitude).
'in'+'stance'='INSTANCE'
'for' acts as a link.
(Other definitions for instance that I've seen before include "Case - isn't acne (anag)" , "Particular case; cite" , "An insect (anag.)" , "Case or example from ancients" , "Case in point" .)
