not really but i guess you want this `#node-input-options` to have the previous selection when the user re-opens the editor?

As I have said in other posts, you need to persist the selection in a node.propertyXXX upon `oneditsave` then in the `oneditprepare` function, when you do the fetch & populate the dropdown, use the persisted `node.propertyXXX` value to re-select the item,

See a full explanation [here](https://discourse.nodered.org/t/input-type-checkbox/43511/16)

So for example...

```auto
              data.forEach((item) =>
                  let value = item.name;
                  let text = item.name;
                  options.push({ v: value, t: text, });
                  $("#node-input-options").append(
                    $("<option></option>").attr("value", value).text(text)
                  );
                  if(value == node.selectedValue) $('#node-input-options').attr('selected','selected'); //<<<<<
              );

```

- `node.selectedValue` is something you need to set when the select is changed.
- that means you need to have an `$("#node-input-options").on("change", function(){ ...}`
- and you need to add `selectedValue` to the `defaults` object
