Icon of child nodes in TreeTable

How can i set no icon for child nodes in TreeTable ? (see attachment) Thanks.

You should call setChildrenAllowed to make item to be leaf

tree.setChildrenAllowed(leafItemId, false);

Thanks a lot Anatoly. It works. I was looking for a solution through css and others, but I could not solve it. Sometimes it is easier than it looks like :slight_smile: thanks again.
