I believe the answer is:

adds

I'm a little stuck... Click here to teach me more about this clue!

'puts together' is the definition.
(I've seen this in another clue)

'poster detective superintendent' is the wordplay.
'poster' becomes 'ad' (short for advert).
'detective superintendent' becomes 'ds' (this could be a standard abbreviation I've not previously seen).
'ad'+'ds'='ADDS'

Can you help me to learn more?

(Other definitions for adds that I've seen before include "Finds the sum (4)," , "Tots up" , "Puts in; tacks on" , "Does summer job" , "Appends or increases" .)

I've seen this clue in The Sun.
