I am importing datafeeds and inporting them into DBSQL.

I have a field 'category' that can vary from day to day according to what data has been imported.

I want to generate a drop-down select box that is automatically populated with the data from the 'category' field- but I need to tell it to only display each entry in the field only once.

ie: I have 10 records all with the same category: 'Fashion' and 10 more with the category: 'Toys'
I want the select box to display the options 'Fashion' and 'Toys' once each.

This select box will be used within a search form.

Can this be done?

Thanks
