2:Issues as need quick assistance

Hello Developer,

Great component after my research and since its updated regularly I have interest in using this in our app.

Two questions for you.

1) Can i keep different width for the left and right menu panels programatically
2) I am tying to run the sample project which gave lot of errors, i set the flags the buidl runs but i see only blank. Can u let me know the fix and Q1 answer.
