Where can I find out more about the `allowCustomOptions` property for the perspective dropdown component? In the [documentation](https://docs.inductiveautomation.com/display/DOC80/Perspective+-+Dropdown), the only thing said about this is:

> Whether a user may enter a custom value to be submitted. Default is false.

That doesn't really tell me anything useful.

If `allowCustomOptions` is `true`, then the user can treat the Dropdown like a Text Field, where they supply their own text. The user needs to interact with the option list as a sort of confirmation. This does not actually modify the available options of the dropdown, but it does change the `value` of the Dropdown to whatever this custom option is.

For example, I have the options “one” and “two” available in a Dropdown. I allow for custom options in that Dropdown. A user attempts to add a custom option of “three”.

The user must actually click the “Create three” option of the Dropdown. The `value` property of the Dropdown will now has a value of “three”. The `props.options` property of the Dropdown has not changed. This new value the user has supplied will be retained even during page reload/refresh, but if the user navigates away to another page and then comes back the `props.value` of the Dropdown will now have reverted back to its “default” value as configured in the Designer.
