How to change the position of a dialog or make a panel modal?

[chernish2]

Thank you very much for such a great framework!
I need something like a dialog but with the ability to position it not in the centre of the screen but at the bottom of the screen. Is there any possibility to change the positioning of a dialog?
I've tried to use panel instead but the problem is it is closing every time I tap somewhere on the screen, outside or inside of the panel. Is there any possibilities to make a panel modal, without auto closing functionality?
By the way I found out that in examples the panel closing only if I push X-button on its header or if I push somewhere outside of the panel, but when I'm trying to use it in my code the panel closes on every tap, including the tap inside of the panel's body. Is it a bug?
