Lets say I have a listbox and its showing values like this:
Now i would like to make the listbox behave like this way:
I would like to show only 'USA' value in the country list Box. But when the 'USA' value is not checked/Selected then It will show the values corresponding other countries to other fields by association. But when 'USA' value is checked then Country field shows the 'USA' value is selected and values corresponding to 'USA' to other fields shows by association.
