Hi,

When you click on a parent node it collapses its children, Could you please clarify what you mean by collapse only child not parent node? and explain a bit more about your use case.

Hi,

You can do something like this:

tbar:{
    items: [
        {
            tag: 'button',
            text:'onClick',
            onClick(){
                gantt.taskStore.records.forEach(task => {
                    if(!task.isLeaf && !task.parent.isRoot){
                        gantt.collapse(task);
                    }
                })
            }
        }
    ]
}
