Create a left menu that hides when shrinking

Create a left menu that hides when shrinking

Hi,
i started using JQuery Mobile only 2 days ago, so sorry if my questions are stupid.

I'm trying to use JQM to create an help site for our software, usable both from desktop and from mobile.

Something relatively simple with:

Header (no problems with that)
A left side menu with arguments
A right side with the argument content

On mobile, the left side menu must disappear if the screen is not wide enough and must be callable with a button on the header.

Questions are:
-What is the best JQM control i can use to create the left menu? A panel is ok for this?
-For showing/hiding left menu based on viewport width i must implement some code, or is managed in any way by JQM?
-For implementing a tree of arguments i thinked to use a  collapsible. It's ok?
-Is there some sample project from where i can start?

Thanks
