In pieces, in the manner indicated below (7)
I believe the answer is:
asunder
'in pieces' is the definition.
(I've seen this before)
'in the manner indicated below' is the wordplay.
'in the manner indicated' becomes 'as' ('as' can introduce a comparison or clarification).
'below' becomes 'under' (synonyms).
'as'+'under'='ASUNDER'
(Other definitions for asunder that I've seen before include "going to pieces" , "Into parts or pieces" , "Sad rune (anag.)" , "(Broken) apart" , "(Rent) apart" .)
