selectlist

I need to know how I could create a drop down list to represent all the categories in my "Categories" table. I have already extracted the names and the values of each category I need, using this LINQ query : var dbcontext = new LNQ2SQLDataContext(); var Q = from P in dbcontext.Categories where P.SUB_CAT == null select P; I can pass this "Q" to my view like this : In Controller : return View(Q); And in the View : @model IEnumerable<MyAppName.Models.Category> But I have no idea how to use @html.DropDownListFor() to make a darn good drop down list out of the model. :| PLUS: I could make a

I am new to using the Html.DropDownList in the MVC framework and am having a hard time understading how to select the data out my database to bind to the DropDownList.
