You can enter search criteria such as <20 or <=12 in the UnitPrice and UnitsInStock fields, or
<C in Product Nameto search for all product names that begin with A or B.
To start with the search screen instead of the grid set $lens->firstState = "FILTER".
We also configure the categories to show as popups by setting filterParams.
This filterParams setting was configured in dynamic edit mode, then generating
the source code and copying the relevant line into the PHP file.
Easy compared to generating it hand!
