Attractive item meant somehow to lure in group leader (6)
I believe the answer is:
magnet
'attractive item' is the definition.
(I've seen this before)
'meant somehow to lure in group leader' is the wordplay.
'somehow' indicates an anagram.
'to lure in' is an insertion indicator.
'leader' says to take the initial letters.
The initial letter of 'group' is 'g'.
'meant' anagrammed gives 'manet'.
'manet' placed around 'g' is 'MAGNET'.
(Other definitions for magnet that I've seen before include "Attractor of iron" , "Great attraction" , "facility for drawing?" , "Lodestone, for example" , "it could be a draw?" .)
