Bedpan Alex ordered that can be enlarged (10)

I believe the answer is:

expandable

'that can be enlarged' is the definition.
(something which can expand or enlarge)

'bedpan alex ordered' is the wordplay.
'ordered' indicates anagramming the letters.
'bedpan'+'alex'='bedpanalex'
'bedpanalex' with letters rearranged gives 'EXPANDABLE'.

I've seen this clue in The Times.
