Hopeless clue Idris mocks (9)

I believe the answer is:

ridicules

'mocks' is the definition.
(ridiculing is a kind of mocking)

'hopeless clue idris' is the wordplay.
'hopeless' indicates an anagram.
'clue'+'idris'='clueidris'
'clueidris' anagrammed gives 'RIDICULES'.

(Another definition for ridicules that I've seen is " Laughs at".)

I've seen this clue in The Times.
