Hi,
I implemented such a behavior. You will need a custom Feature for this. Decide of a default collapsed size. First you will remember the initial size in properties of your pictogram-element

		PictogramElement pe = moduleShape;
		int width = pe.getGraphicsAlgorithm().getWidth();
		int height = pe.getGraphicsAlgorithm().getHeight();		
		Graphiti.getPeService().setPropertyValue(pe, "initial_width", String.valueOf(width));
		Graphiti.getPeService().setPropertyValue(pe, "initial_height", String.valueOf(height));
		Graphiti.getPeService().setPropertyValue(pe, "isCollapsed", "true");

then resize it

                ResizeShapeContext context1 = new ResizeShapeContext(moduleShape);
		context1.setSize(100, 100);
		context1.setLocation(moduleShape.getGraphicsAlgorithm().getX(), moduleShape.getGraphicsAlgorithm().getY());
		IResizeShapeFeature rsf = getFeatureProvider().getResizeShapeFeature(context1);
		if (rsf.canExecute(context1)) {
			rsf.execute(context1);
		}
		addConnectionOccurences(moduleShape);

and set its children invisible if you need to. Good Luck
