Navigating through a list or library with dozens or hundreds of items or folders can be a tedious task. There are a few ways to make it easier to find the information you are looking for. One unique way is to build a rolodex to filter the list items conveniently.
The rolodex is configured by using a Query String Web Part and Content Editor Web Part to filter a list or library. The high-level steps to accomplish this are:
Create an “Index” field in the list or library.
Add a Query String Filter Web Part, a Content Editor Web Part, and the web part for the list to a site page.
Add code to the Content Editor Web Part with links that reload the page with the query string value.
Configure the Query String Filter Web Part to send data to the list web part.
