How to select dropdown of an activity module for CSS modification

Hi Kyle,
I am having problems with selecting the drop-down menu at the right hand side of a stream.
Here is my setup:
Activity stream outputted by a module (module has a unique pre-fix so can be selected using CSS)

I need to be able to change the fontawesome icon (if possible also the content) of the menu of each activity within that stream.
I know how to change it once I have selected the stream that I want.

Problem: I cannot select the menues from the stream that I want.

Any way how to solve this?

Menus are JavaScript. They existed attached to the body element of the page. You will not be able to style them based off a specific module. You'll only be able to style them globally.
