Selected depot layout (5)
I believe the answer is:
opted
'selected' is the definition.
(I've seen this in another clue)
'depot layout' is the wordplay.
'layout' indicates anagramming the letters (an alternative layout of the letters).
'depot' is an anagram of 'OPTED'.
(Other definitions for opted that I've seen before include "Chosen - elected" , "Chose from depot" , "Selected from depot" , "Depot (anag.)" , "Plumped (for)" .)
