I would like to dynamically load Select options for locations based on a subsidiary selection. the field.addSelectOption is not available on the Client Script per the documentation. any ajax type functionality

If anyone has done any type of dynamic loading of select field based on selection on another field, please let me know how you did that.

```
var field = currentRecord.getField(...)
field.removeSelectOption(...);
field.insertSelectOption(...);
```

User Event Script before load is your best bet

`form.getField().insertSelectOption(...)`

With this method, you would refresh the page once the subsidiary is set

Thank you <@U8CT0V220> and <@U5UG9SYNQ>! I like these options!

i should clarify that the method I mentioned uses `addSelectOption()`

As an alternative approach, I recommend no scripting

Use a custom field and use the filtering options

You can filter the select options based on the value of another field

In your example, you can add a multiple select field on the location which stores the subsidiaries that are select able on that location.

Then on your custom location field, you would add a filter on the custom location field where its value is equal to the subsidiary field you wish to filter on

Thank you <@U5TF1GQ20> ! I hadn't looked into Multiselect but looks like an interesting option. It is not available on suitelets but i might use it for other projects.
