item_speed.setHeight(menu_length * 25);

item_speed.setControl(composite_speed);

Composite composite_speed = new Composite(expandBar, SWT.NONE);

Button item_button = new Button(composite_speed, SWT.NONE | SWT.PUSH);

item_button.setText(lable);

item_button.setData(WidgetUtil.CUSTOM_VARIANT, "expandItemButton");

formData.bottom = new FormAttachment(100,0 );

formData.left = new FormAttachment(0, 0);
