The list for a dropdown is a dataset like any other. Use [system.dataset.toDataSet()](https://docs.inductiveautomation.com/display/DOC79/system.dataset.toDataSet) to create one from scratch.

Depending on the layout of your dataset (number of columns and datatype of the columns), the behaviour of the “selectedValue”, “selectedStringValue” and “selectedLabel” can differ though.

See the docs: [https://support.inductiveautomation.com/usermanuals/ignition/index.html?input\_pmicombobox.htm](https://support.inductiveautomation.com/usermanuals/ignition/index.html?input_pmicombobox.htm)
