Hello IBO community,
I am sorry for my naivety.
But, please, explain me sequence of steps to use dropdown menus in
IB_Grib. I learning samples carefully but can't understand what
properties I need ? How to link 2 TIB_Query - KeySource and KeyLinks,
or I must specify params in detail query with name corresponding to
field name in master query ?
Or redirect me please to right documents.

I try to migrate from IBX and old templates confuse me, obviously.

Thanx in advance.
