Vote inside drab children's complex (7)

I believe the answer is:

electra

I'm a little stuck... Click here to teach me more about this clue!

'complex' is the definition.
(Electra complex is an example)

'vote inside drab' is the wordplay.
'vote' becomes 'elect'.
'inside' indicates the central letters.
The centre of 'drab' is 'ra'.
'elect'+'ra'='ELECTRA'

'children's' is the link.
This may not be right. It may be part of another bit of the clue.

Can you help me to learn more?

(Other definitions for electra that I've seen before include "Female avenger" , "type of complex" , "Greek heroine (with a complex!)" , "mythological princess" , "Treacle (anag) - daughter of Agamemnon" .)
