Suppose I have a form dropdown for selecting an Azure subscription, and then a multi-select dropdown that lists the resource groups of that selected subscription.
If I change the value of the Subscription dropdown, any selected items in the Resource Group (dependent) dropdown remain - even though they are now invalid relative to the changed value of the parent dropdown. Though the options have now changed, it is still populated by the previous selection.
Please add functionality such that, in this example, the 'Resource Groups' dropdown would have all of its selections cleared as a result of the 'Subscriptions' dropdown being changed.
