jquery accordion with columns collapse
I put together two jquery technics:
- Masonry
salvattore.js to put my boxes with content in the right order in 3 columns (working fine)
-
Accordion js to expand my hidden text (problem!)
This is my
working jsfiddle for that.
But my problem is: When I toggle one box in first column after that in second column and after that in third column some Title box Autollapse function and toggle function gonna crazy. In one column working fine, but how to repair that functionality in 3 columns.
I guess the problem is in '.acco' class which is the parent of my items.
Please help me with that. I would like open only one box at the time and other autocollapse.
What should I change in js script?
Please, any clue or ideas?
