Collapse layers group when starting the app

[ErfanGoharian]

I managed to have a grouped layers list, however, the problem I have is that when I use the "openAll" option (not the drop-down option), and because I have so many groups, when I start the app it shows all the groups open (first figure). I can collapse them manually (figure 2), but I am trying to find out how can I have just one expanded when I start the app?

Thanks, Robert Scheitlin, GISP. I exactly did what you said, and also checked these codes as well (https://community.esri.com/thread/237493-is-it-possible-to-collapse-multiple-layer-lists-by-default ). I still get strange results, where the titles of all my sub-groups are gone!

Here is also part of mu Config.json code:

Erfan,

   So it looks like you are having the issue that has been addressed in the second threads code. The important part is the setTimeout in the code below (line 24):

      createFoldableBtn: function() {
        this.foldableNode = html.create('div', {
          'class': 'foldable-btn',
          'role': 'button',
          'aria-label': this.headerNls.foldWindow,
          'tabindex': 0
        }, this.btnsContainer);

        this.own(on(this.foldableNode, 'click', lang.hitch(this, function(evt){
          evt.stopPropagation();
          this.onFoldableNodeClick();
        })));

        this.own(on(this.foldableNode, 'keydown', lang.hitch(this, function(evt) {
          if(evt.keyCode === keys.ENTER || evt.keyCode === keys.SPACE){
            evt.stopPropagation();
            this.onFoldableNodeClick();
          }else if(evt.keyCode === keys.TAB && evt.shiftKey){
            evt.preventDefault();
          }
        })));

        if(this.openfolded){
          setTimeout(lang.hitch(this, function(){
            this.onFoldableNodeClick();
          }), 500);
        }
      },‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I exactly have the same code there:

Still, I am getting the strange behavior from this though!

Sorry I am not sure then.

When I start the app it seems it wants to load it as I want (we expect), but suddenly it goes wrong:((
