Using bootstrap select2 with JqGrid form

I didn’t known select2 plugin before. I tried it and can’t found any problems. I suppose that you have problems with the width just because use used too large parameter of width function in $(element).width(260).select2();.

The demos: one without Bootstrap and another one with including of Bootstrap 3.0.0 works without problems. The select looks like on the picture below

I used in the demo

formatter: "select", edittype: "select",
editoptions: {
    value: "FE:FedEx;TN:TNT;IN:Intim",
    defaultValue: "Intime",
    dataInit: function(element) {
        $(element).width(122).select2({
            // add "ui-widget" class to have the same font-family like in
            //     jQuery UI Theme
            // add "ui-jqdialog" class to have font-size:11px like in other
            //     items of jqGrid form
            dropdownCssClass: "ui-widget ui-jqdialog"
        });
    }
},
stype: "select",
searchoptions: {
    value: "FE:FedEx;TN:TNT;IN:Intim",
    defaultValue: "Intime",
    dataInit: function(element) {
        $(element).width(122).select2({
            // add "ui-widget" class to have the same font-family like in
            //     jQuery UI Theme
            // add "ui-jqdialog" class to have font-size:11px like in other
            //     items of jqGrid form
            dropdownCssClass: "ui-widget ui-jqdialog"
        });
    }
}

and added the following CSS to improve the visibility (on my personal taste)

.ui-jqdialog .select2-container .select2-choice {
    height: auto;
    padding-top: 1px;
    padding-left: 0.2em;
    padding-bottom: 2px;
    line-height: 15px;
}
.ui-jqdialog .select2-container .select2-choice .select2-arrow b {
    background-position: 0 -4px;
}
.ui-jqdialog.select2-drop { padding: 0px; }
.ui-jqdialog .select2-results .select2-result-label {
    padding: 2px;
}

Additionally I added some more CSS in the demo which used Bootstrap CSS:

.ui-jqgrid table {border-collapse: separate}
.ui-jqgrid .ui-pg-input, .ui-jqgrid .ui-pg-selbox {height: 17px}
.ui-jqgrid .ui-pg-table {padding-bottom: 0}
