[luci] a taboption depends on a taboption belongs to other section?

[Le Tran Dat]

I've search the source code of LuCI and didn't find any code that use
variable from other sections.

Could anyone suggest me a way to automatically change a taboption value
depends on another taboption value of another section?

Thanks,
Dat
