Oh, I found, ListDatasource is delphi components DBLookupComboBox
attributes. Moreover, the situation was not encouraging, Lazarus has
not yet developed this component. I would like to see:

You have probably only set the datasource+field of the field in which<br>
you want to store the data. You also have to provide a datasource and<br>
two fields (one with the key, one with the value you want to show) to<br>
generate the list from which you want to choose. Look at ListDatasource,<br>
KeyField and ListField.<br>
