I use ordering by multiple columns:

$opt[“multiSort”] = true;

I would like to add one specific colmun to the end of the column list selected by user. For instance if the user clicks Title and then Department, I want the final order by clause to be:

order by title, department, id

I tried to set:

$grid[“sortname”] = ‘id’;

But it seems to end up as:

order by id, title, department

Is there some way to do it other way round?
