How to avoid tabulation on a closed toogle hamburger menu?

I have a static web with html, css and js.

As an accessibility request I must avoid the tabulation to read what´s inside a closed toogle menu.

As well, once it´s open I must avoid the tabulation to exit the list of the menu until you select one or you exit the menu with esc or the exit button.

I actually don´t know how to approach this.
