OAP's idle fancy brought in as a digression (8)

I believe the answer is:

episodal

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

'in as a digression' is the definition.
I can't judge whether this definition defines the answer.

'oap's idle fancy' is the wordplay.
'fancy' is an anagram indicator.
'oaps'+'idle'='oapsidle'
'oapsidle' with letters rearranged gives 'EPISODAL'.

'brought' is the link.

Can you help me to learn more?
