How to use materialize js components with meteor

I use materialize framework for my front-end meteor app.

I have installed materialize package and jQuery package, and I can use componants that use only css but when it came to js componants I can’t find where to put the Initialization.

For example I want to add dropdown I take the HTML code and I put it inside my HTML file .

After that I didn’t know how and where can i put the js or jquery .

So I want to know where and how I use the js or the jquery lines please.
