How to invisible collection data according to drop down selection without hitting database?
Hi Everyone,
I want to invisible collection row depend upon drop down select without hitting DB.
I know its possible on one service with drop down as a parameter but it every time it will hit the dB when i select drop down option i don't want this,

Please check above image which having workout data in collection.
On mashup loaded it will load all workout data once time then, When i select beginner i want to show only those workout data related to beginner without hitting database and remaining data are invisible.
same goes with other two option.
How can do that?
Thanks in advance
