Solution

  • I don't know which API's ComboBox you're using since vanilla GWT doesn't have a ComboBox, but I'd guess it's not possible to do this unless you change the ComboBox class itself/write an actual MultiSelectComboBox class. Unless your version happens to have an "enableMultiSelect" method already in-built, but you probably wouldn't be asking here then.

    If it helps, I found this thread which seems similar to what you're describing.
