To expand a content given a coord e.g: 1-1, put the coord in the input and click the expand buttom
Awesome dynamic, recursive, customizable and multilevel Accordion Menu for AngurlarJS, that builds up from a JSON object and an optional configuration object. You can download the project for a live demo in the example folder (don't forget to bower install dependencies) and for better understanding.
No jQuery needed
You could set before/after topContent/bottomContent in the accordion config object to set a scroll back to top buttom (or whatever you like), given that you only need to set the value once and it will be in all the contents of the accordion.
