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

'list best type of desks?' is the definition.
I can't tell whether this definition defines the answer.

'list best' is the wordplay.
'list' becomes 'roll' (roll is a kind of list).
'best' becomes 'top' (top can mean the very best).
'roll'+'top'='ROLL-TOP'

Can you help me to learn more?

(Other definitions for roll-top that I've seen before include "Trollop! (anag)" , "Type of desk" , "Sort of desk" .)

I've seen this clue in The Guardian.
