Popup notification component.

Hello

We have a requirement to create a component to broadcast messages to users in the form of a "pop-up window" on the page.

Authors should have the ability to edit the pop-up component message, and on publishing , the message should be be displayed at the center of page as a dialog only , and should not occupy any place in the actual page content.

We should be able to add multiple messages in a page.

Is there any component to achieve this messaging functionality? OR a suggested approach.

I have tried using jquery to achieve the pop-up functionality, and the pop-up is displaying as expected in author.

However, my concern is on how the component can be displayed only as a popup and not use up any portion of the page in the publish sites.

Any help is appreciated.

Thanks.
