trying to use multiple search with jqgrid but only single search GUI pops up

i want to implement more advance search than the filter toolbar in jqgrid so i changed my code to set multipleSearch: true:

jQuery("#grid").navGrid("#pager",
        { multiple开发者_C百科Search:true, add: false, edit: false, del: false },
        {}, {}, {}, {}

i do get the Search Icon in my footer toolbar

but when i click on it, i just get the single field search GUI.

does anyone know why this would not show up the multiple search GUI? Am i missing some extra plugin or config setting ?

You should use multipleSearch:true inside another parameter of navGrid:

jQuery("#grid").navGrid("#pager",
        { add: false, edit: false, del: false }, // navGrid options
        {}, // edit option
        {}, // add options
        {}, // del options
        {multipleSearch:true}  // !!! search options !!!
);
