TAdvDualListBox and TAdvListEditor are two quite different controls, already from the perspective of screen estate being taken. I understand that also in the case of TAdvListEditor or combobox, you want that the vertical space taken by the control grows as the number of selections grow?
As we don't have a filtering capability on TAdvDualListBox, perhaps dynamically managed TAdvComboBox instances in a TScrollBox or a TPanel that grows its vertical size might be the obvious choice. Sadly, we do not have at this moment a control available that has all this functionality already embedded.
