Exposed filters with dropdown selections I have a project where I've created a View with some basic information, showing for example Year, Manufacturer, Product Type. They are all custom text fields. I can expose a filter on them which lets me manually enter in a search, for example, 2008 for year and it correctly shows me all the entries for 2008.

Is there any way to have these fields available as a dropdown selection based on the content saved within each node, eg so that the Year field shows 2001, 2002, 2003 ..... 2012 etc, or Product Type shows "Table, Chair, Lamp etc" that the user can choose from? I'm fairly new to using Views and struggling to find an answer.

I'm using Drupal 7 and Views 3.3.
The problem here is that the fields are custom text fields. If the "product type" field was of the type "List (text)" instead it would be a drop down in Views when exposed.

Maybe the product type would be good to have as taxonomy terms instead? Then product types could easy be added to the vocabulary as the site grows. The field in your content type would then be a "Term reference" to the Taxonomy vocabulary product type. If the product types rarely or never change you could stick with "List (text)"

I would probably make the field year into a date field or taxomomy, or list (integer).

I hope you see where I am trying to go here, the fields needs to be of the correct type for Views to be able to interpret the fields correctly and "automatically" give you dropdowns when the filters are exposed etc.
