An Expandable event utilises Flash overlays like a Floating event but is more versatile and content-rich as the user opts in by clicking on the inline element first.
Upon loading the Yahoo! UK Front Page, the user is shown the inline element. When the user clicks on it, the Expandable overlay appears and covers the inline element and the content around it.
The Expanding overlay must contain a close button that contains the word “Close”. The close button must be clear and visible for the duration of the Floating overlay. We may also move the close button or use our default close buttons to ensure the best user experience possible.
A video can also play in the Expandable overlay with sound automatically on, as the overlay itself is user-click-initiated.
Please provide video asset as FLV (2.2MB or below) or uncompressed AVI or MOV at 30 seconds. Video asset specs for videos in the Expanded panel are negotiable, please liaise with your Yahoo! Sales representative to work out specs that will meet your needs.
Audio (sound only) is also available in the Expandable overlay. The audio asset should be supplied as a WAV or MP3 at around 100KB. There must also be controls to mute the audio.
Extra Flash assets can also be loaded into the Expandable overlay after it loads. The extra assets should be around 100KB each and the total number of extra assets should be less than 5. Preloaders are highly recommended.
