jQuery Grid Plugin - jqGrid

Greetings all. I've got an editable form, and I'm using the "add" button that comes by default in the pager. I know I'm missing something stupid, but I can't figure out how to customize the size of the "add" form when it pops up. The "edit" form is sized correctly from the options I pass in editGridRow. (I'll post all my code below).

Another question: is basic form validation baked into the form editing? for example, I just want to mark some fields as required. I tried using required:true in my colModel, but that appeared to have no effect.

Finally, is there a way to provide default values for form fields when "add row" is clicked and the new form pops up?

thanks!

Marc
