Inputs

Option	Type	Default	Comment
highQualityPath	string		The path to the high-quality image or content to be displayed, which seamlessly replaces the current picture when opened.
fixedHero	boolean	false	Specifies whether to use the fixed-hero mode when absolute positioning is not effective due to overflow issues.
supportedFormats	string[]		An array of supported image formats, which is only required when using the <picture> element where the browser automatically selects the format.
backdropPosition	'documentEnd'	'beforeHeroItem'	Insert backdrop at this position.
browserSupportAvif	boolean		If you have already manually determined whether the browser supports AVIF, you can set it using this option. Otherwise, the package will automatically perform the check. This option is only required when supportedFormats contains values.
browserSupportWebP	boolean		If you have already manually determined whether the browser supports WebP, you can set it using this option. Otherwise, the package will automatically perform the check. This option is only required when supportedFormats contains values.

Outputs

Option	Type	Comment
openHero	output	Triggered when the hero animation starts.
closeHero	output	Triggered when the hero animation ends.
