fleshed out

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

'added details to story' is the definition.
I can't tell whether this definition defines the answer.

'crazy hotel feuds' is the wordplay.
'crazy' indicates an anagram.
'hotel'+'feuds'='hotelfeuds'
'hotelfeuds' with letters rearranged gives 'FLESHED OUT'.

'of' is the link.

Can you help me to learn more?
