event in collect function

Hi, will be cool to have an opportunity to pass event in colect func.
In my case i have more than 1k elements in list and every element i need to wrap and bind triger to be able to recognize on which element right click was made. It causes some problems with performance.
If i could wrap whole list and bind trigger to list and by event check with data art on which rlrmrnt click was made. That will be cool.

Start by locating the collect function and tracing how context-menu events are currently bound for each element. Define how an event passed to collect should identify the clicked item, then verify that the list-level binding avoids per-element handlers and preserves the existing hook behavior.
