default to collapsed view?

[abenrob]

Is it possible to have the tree default to collapsed on creation?

Add this:

    this.foldAll= function(){
      var f=document.getElementsByClassName('jstFold');
      for (let i = 0; i < f.length; i++) {
        const it = f[i];
        setTimeout(() => {
          it.click();
        }, 0);
      }
    }

And call it after create, and will work.

this.foldAll= function(){
var f=document.getElementsByClassName('jstFold'); //should be jstCollapse NOT jstFold (Apr2020), then it works well
