Filters Collection includes a full range of programmable List Filters that let portal visitors quickly filter the data received by any Web Part that supports standard Web Part Connections, without the heavy cost of Enterprise features or the resource drain that comes with running Excel Services. Instead, the Filters Collection lets you customize Choice, Date, Text, and Current User filters, connect them to a Web Part, and have them up and running in minutes. Best of all, the collection also includes the Bamboo List Filter Web Part, which enables you to create complex, multi-column filters for List View Web Parts that are easy to make, and even easier to use.
