NgcGui possibilities

Hello,

i found this video on YT, and see in the ngcgui has more input box than 30, and have a checkbox.
I try to do my special ngcgui and for this i need some options.

- How can i put checkbox in ngcgui?
- How can i organize input boxes to be in one column (more than 10 in one column).
- Can i put other objects, like dropdown menu, radiobutton or something other?

Thanks,
Attila.
