there is no css included in your code fragment. Verify, that you have following css included:
jQueryUI-css coresponds used jQueryUI version and theme. For example, “themes/redmond/jquery-ui-1.7.2.custom.css”
jqGrid css like “ui.jqgrid.css”
optional, if you use searching possibilities of jqGrid, include “jquery.searchFilter.css”
optional, if you use possibilities like 'gridResize' etc.: “ui.multiselect.css”
moreover, because you use 'gridResize' feature, you have to include “ui.multiselect.js”. If you use searching possibilities of jqGrid, include “jquery.searchFilter.js” also.
For some reason, I missed posting the css section in the question. However, I did have it in my codes. I took your advice and added multiselect js and css files. Still not working. Here is my entire section:
The error is probably in the part of you code, which you not describe here. In my code, for example, everything works OK. If you prepare a small html/javascript code without any server code (you can set datatype to 'local' or 'clientSide' and fill table with at least one row of test data with respect of addRowData). So one could be easy localize and fix you problem.
