Grids are an excellent way to display information in your Knack apps. Especially, since they offer many features to further organize your data for easy understanding.
For example, let's say you want to create a grid that quickly shows which donors are making the most donations. So you start with a grid that shows all donations:
It's not a bad start, but it's not easy to tell who your best donors are. That's where a feature like grouping can make all the difference.
Grouping allows you to group records by a common value in selected grid columns. Here’s what your grid will look like when it's grouping the donations by donor:
With a header row for each donor and their donations listed below them, you can see who’s in the giving spirit at a glance.
Plus, since the "Amount" column was already totaled using a row summary, the grouping now shows the total per donor. Though there’s still a complete total for all donors at the bottom of the grid:

Other good resources can be found in our About Your Database and Working With Pages sections of the knowledge base.
