Urgent looking for idea how to implement Index Page visualy like this https://www.wix.com/code/home/example/Table-Index but
with possibility to expand items on the same page instead of to go to separate dynamic page. The "container" to expand will have text and graphic elements inside with additional expandable sub-list (variable number of items).
For example: Filtered list of authors-> each author expands to "All about author" + list of works->each work expands to "All about work".
Any idea would be greatly appreciated.
