We use Application Designer 2.1 and would like to have a combo box showing more than 1 line that allows to select more than one value (“multi select”). From the documentation we conclude that it should suffice to set “size” to a value > 1. The visual part of the rendering seems to be ok - we see more than one line but we can’t select more than one line. The generated html is a html “select” element. We’d expect this element to have a “multiple” attribute to provoke the multi selection stuff in the browser, but there’s none.
Presumed we’d be thinking in the correct direction with the select element and its multiple attribute - we don’t know as well what type the value property of the COMBODYN2 should be to be able to receive the multiple selection values.
