Detectives eating lots turned up full of beans (7)

I believe the answer is:
dynamic
'detectives eating lots turned up full of beans' is the definition.
I can't judge whether this definition defines the answer.
'detectives eating lots turned up' is the wordplay.
'detectives' becomes 'CID' (abbreviation for Criminal Investigation Department).
'eating' means one lot of letters goes inside another.
'lots' becomes 'many' (many means lots of something).
'turned up' shows that the letters should be reversed in order.
'cid' placed around 'many' is 'cimanyd'.
'cimanyd' back-to-front is 'DYNAMIC'.
Can you help me to learn more?
(Other definitions for dynamic that I've seen before include "Constantly changing" , "Powerful and vigorous" , "Go-getting" , "High-powered" , "Having power" .)
