I am new to InfoPath.According to the method(http://www.bizsupportonline.net/infopath2003/shrinking-dropdown-list-repeating-table-infopath.htm),the filter “not(.= xdXDocument:get-DOM()+XPath” works in parent
repeat table, but all child repeat tables share a common drop-down list.
How to modify the filter to creat a independent shrinking drop-down list in child repeat table by infopath?
