I have a biological inventory site built in WebDirect for multiple labs. Scientists are able to have numerous inventories like tabs in a spreadsheet; this has been accomplished by using flex fields in FileMaker. Flex fields are a set of fields that can be named anything and there is a corresponding set of FileMaker fields to display the caption of the flex fields. This is where sliding comes in to play. When a flex field is not in use, it leaves a space on the layout because it is hidden. Could report sliding be used to slide active fields over or up/down over hidden fields?
