This format handler will style a Select mask column with the down arrow indicator. This replaces the default @lookup format handler for a select mask column
var selectFormat = function(objDiv, strCDFKey, objMatrix, objMatrixColumn, intRowNumber, objServer) {

var objNode = objMatrix.getRecordNode(strCDFKey);
if (objNode) {
var strValue = objMatrixColumn.getValueForRecord(strCDFKey);
var lookupNode = objMask.getRecordNode(strValue);
objDiv.innerHTML = jsx3.util.strEscapeHTML(

}
objDiv.style.backgroundImage = "URL(JSX/images/select/arrowmask.gif)";
