[Feature]: Add mountNode property to Combobox #28625
Description
Library
React Northstar / v0 (@fluentui/react-northstar)
Describe the feature that you would like added
The Portal component's mountNode property lets the user specify the target DOM node into which the Portal/popover/flyout will render. This is a very useful property for cases where <body> or inline won't do, such as the PowerApps Canvas surface.
The InfoButton component already has this available; it's exposed via the larger popover property. Something like that would be agreeable for Combobox, but I'll leave the implementation details up to the experts.
Have you discussed this feature with our team
