shiny.fluent (version 0.4.0)

Overlay: Overlay

Description

Overlays are used to render a semi-transparent layer on top of existing UI. Overlays help focus the user on the content that sits above the added layer and are often used to help designate a modal or blocking experience. Overlays can be seen used in conjunction with Panels and Dialogs.

For more details and examples visit the official docs. The R package cannot handle each and every case, so for advanced use cases you need to work using the original docs to achieve the desired result.
