Filter by Category

Hi,

I have created a 'list' page where the number of records is making the page a bit long. I am trying to create an index page where I can select a number of records by category. So I have created a category 'section' and created an index page from this that lists the categories. I have also added a category field (field type: list) in my data.

The problem is how do I make this work. When I click on a category on my index page I want it to filter the records and only show the records that are in the category selected.

Hope this makes sense,

Roger
