@mlynch any chance this can be reviewed and merged soon, I would like to point my bower to main repo rather than my personal one.

Thanks

Could you add some documentation about your directive?
Also, if I have left and right menu, how can I toggle it?
And, how to hide menu by tapping on content, not just by slide to left?
Finally, you have error in line 175

Thanks @EAndreyF

1. It's not my directive, I am just pushing some fixes to it. But I will try to write a basic docs
2. You can toggle it by changing html attribute on directive. check my plunkr
3. to hide by tapping on content is not implemented atm, but can be done easily
4. I don't see any errors on line 175..?
