I have a script in which I need to reset the options of a dropdown element.

When I try to `del` or `remove` an options index I run into errors.

How do i do this?

Modifying a list while iterating is always a problem, whether on a dropdown's options or anywhere else in jython. For major updates to such a list, build a new complete list.

In this particular case, you can probably do:

```python
del self.props.options[1:]

```
