UI design pattern for multi level grid
问题 currently I have a requirement to display related items in a multi level grid. that is great grandparent -> grandparent-> parent-> child For example: Country-> state->City->Street is the order of display. The proposed solution is to display all these in a multi level grid (4 levels maximum). Country -> state ->City ->Street Since I am not comfortable with this solution with respect to usability aspect, I am looking for a UI design pattern that will break up the display into logical units.
