I set the required option to my password field dynamically:
$("#name").jqGrid('setColProp', 'password', {
    editrules: {
        required: true
    }
});
And it work 's fine. But I can't set the elmsuffix:
$("#name").jqGrid('setColProp', 'password', {
    formoptions: {
        elmsuffix: ' *'
    }
});
What am I doing wrong?
