Folding is a way to display your rendered FoldingText content on the web. See a live demo here.
I've implemented what was the most important features for me: folding, tag filtering and todo lists. Feel free to fork & send pull requests if you want additional features.
Include "folding.js" and "folding.css". Folding.js exports one function foldIt. To use it you can either pass it a node list foldIt(document.getElementsByClassName('post-content')), a single element foldIt(document.getElementById('fold-this')) or simply call foldIt() to have it process all elements with the class "folding".
// Process all elements with the class "folding".
foldIt();
// Process a single element
foldIt(document.getElementById('fold-this'));
// Process all elements in a node list.
foldIt(document.getElementsByClassName('post-content'));
Headlines with the class "folding-collapsed" will start out collapsed.
