Hello Michael,

The suggested feature is not in our roadmap yet. We will continue to monitor the interest in the request and the votes the issue gathers and based on the demand we will consider adding the feature for implementation.

Hello,

I am afraid that the setOptions method could not be used for all the properties in every widget. As described in the following link from the documentation - Depending on the widget, some properties may not be changed, and the method's implementation varies for each widget.

- https://docs.telerik.com/kendo-ui/api/javascript/ui/widget/methods/setoptions

Thus, I am changing the type of the thread to Feature Request. This way, the other users in the community could vote for the issue.

If it is suitable for your scenario you could try to destroy and recreate the Popup widget with the new options.

- https://docs.telerik.com/kendo-ui/intro/widget-basics/destroy

Here is a Dojo example where the approach from the article is used for the Popup widget.

I hope this helps.
