jQuery Grid Plugin - jqGrid

Hi

I wonder if the following would be possible.

At this moment I'm using the custom search feature with its own filtermodel.

Following the documentation I need to use the surl attribute to construct my selectbox. This causes  a async request.

However, in the search configuration used by single/advanced search it is possible to use the field value and do something like this:

Would it be possible to also add a value attribute to the filtermodel options of the custom search?

In that way I could render the data serverside and avoid the ajax call to the select form.

Thanks !
