Side menu in myTabs layout?

I’m using the ionic myTabs template here: http://plnkr.co/edit/qYMCrt?p=preview. On the friends tab, I want to add a side-menu so I can filter results.

I’m not sure how to add a side-menu to the myTabs layout. I tried following some instructions here: http://codepen.io/benallfree/pen/JLehx but it doesn’t seem to apply to my layout. Any help would be appreciated as I’m new Ionic and using it for a final project due in a few days.
