qMultiSelector : Overview

Overview
qMultiSelector contains one or more qSelector web parts. When multiple selectors are displayed, one selector will filter the next one. For example, when if you have two lists called Projects and Phases, the first selector displays the data from the Projects list, while the second selector displays the data from the Phases list. Only phases that belong to the project selected in the first selector are displayed.
qMultiSelector supports multiple languages. You can define a different title for different languages using the Resource List and the Title Resource ID properties. The culture for the page can be defined by appending the Culture HTTP parameter to the page URL. For example:
http://hostname/sites/sitename/default.aspx?Culture=en-US
qMultiSelector implements the row provider interface. It can provide a row to another Row Consumer web part or a filter to another Filter Consumer web part.
The List Form implements IRowProvider interface. It can provide a row to another Row Consumer web part or a filter to another Filter Consumer web part.
 
The List Form also implements IWebPartRow interface, and it can provide a row to another web part, such as qListView.
