I'd try Len, dancing in a fashionable manner (8)

I believe the answer is:

trendily

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

'in a fashionable manner' is the definition.
I can't judge whether this definition defines the answer.

'i'd try len dancing' is the wordplay.
'dancing' indicates anagramming the letters.
'id'+'try'+'len'='idtrylen'
'idtrylen' is an anagram of 'TRENDILY'.

Can you help me to learn more?

(Other definitions for trendily that I've seen before include "in modern style" , "Coolly" , "voguish way" .)

I've seen this clue in The Daily Express.
