Lightbox components are a standard part of the Salesforce UI, but they’re not easily available (until now!) for your own code.
Salesforce lightboxes have the following properties:
- They “grey out” the rest of the page behind the component, making the page unclickable until the lightbox is dismissed
- They can be dragged around the screen by dragging on the title bar
- They can contain any content you like, including a Visualforce page (use an iframe inside the lightbox)
