The module which i want to talk about in this post adds the Autocomplete feature to the CCK Text/Number fields.

Download the module @ here and Install it

 

Edit any content type and create a new text field. I would like to create a color attribute.

 

Configure the newly created color field.

 

The Autocomplete CCK field is now ready.

 

Done =)
