Expand / collapse a group via JavaScript?

I have extended the script from @Vova_p and collected some related scripts here:

https://gist.github.com/MarshySwamp/a39e3e1efee41174b3b92ee68c40fcd8

the suggestions listed here so far work under limited assumptions. But closing a group this way removes a lot of information from the group: layer styles, lock status, color, blendIf, opacity changes, etc.

Is there no JSX command to do it without altering the group?

Hi =)

I had this broblem too. But i found a answer. It strange a little bit, but it works.

So, we have a layers in the group, and group is expand. Group is a acive layer.

var groupname = app.activeDocument.activeLayer.name // remember name of group
var idungroupLayersEvent = stringIDToTypeID( "ungroupLayersEvent" ); // this part from  Script Listene -- ungroup group
var desc14 = new ActionDescriptor();
var idnull = charIDToTypeID( "null" );
var ref13 = new ActionReference();
var idLyr = charIDToTypeID( "Lyr " );
var idOrdn = charIDToTypeID( "Ordn" );
var idTrgt = charIDToTypeID( "Trgt" );
ref13.putEnumerated( idLyr, idOrdn, idTrgt );
desc14.putReference( idnull, ref13 );
executeAction( idungroupLayersEvent, desc14, DialogModes.NO );
var idMk = charIDToTypeID( "Mk  " ); // this part from  Script Listene --  group selected layers
var desc15 = new ActionDescriptor();
var idnull = charIDToTypeID( "null" );
var ref14 = new ActionReference();
var idlayerSection = stringIDToTypeID( "layerSection" );
ref14.putClass( idlayerSection );
desc15.putReference( idnull, ref14 );
var idFrom = charIDToTypeID( "From" );
var ref15 = new ActionReference();
var idLyr = charIDToTypeID( "Lyr " );
var idOrdn = charIDToTypeID( "Ordn" );
var idTrgt = charIDToTypeID( "Trgt" );
ref15.putEnumerated( idLyr, idOrdn, idTrgt );
desc15.putReference( idFrom, ref15 );
executeAction( idMk, desc15, DialogModes.NO );
app.activeDocument.activeLayer.name = groupname // recall group name

P.S. Sorry of my english. It doesn't my mother tonque.

The work-a-round could be these scripts here.

buliarca's scripts BCM Tools

If I remember correctly there was a work-around, probably the thread was over at the now-defunct ps-scripts.com.
