Hi,

I’m filling a controlp5 dropddownlist with columns from a CSV file.

```auto
 for (int i=0; i<columns.length; i++) {
    time.addItem(columns[i], i);
}

```

But when I load a different file, the controlp5 dropdownlist should show the columns of that file. How do I remove all items from the dropdownlist so that I can add the items from the new file to an empty list?

Thanks

That was actually really easy.

```auto
time.clear();

```

did it for me!
