sorry about that.
here's a fiddle of a grid using jquery 1.11.0 and jqgrid 4.6.0 http://jsfiddle.net/46jEe/1/
and here's a fiddle of a grid using jquery 1.7.2 and jqgrid 4.4.3 http://jsfiddle.net/49Z8p/3/
the jquery version and jqgrid version are the only two things that i changed but as you can see, the older version show the filter toolbar while newer one does not. if you look at the console (on firefox) it says TypeError: a.jgrid.bindEv is undefined – jquery.jqGrid.min.js:215
hope this helps
