Native widgets are those widgets provided by the platform on which the OPI is running. They are rendered by the OS or RAP platform (WebOPI) instead of drawing it on canvas as other widgets in BOY. Usually, they not only have better looking, but also have significantly better performance in WebOPI, so it is strongly recommended to use native widgets as much as possible for OPI to be ran in WebOPI. In OPI editing mode, the widget is disabled so user can click on it to select it, but it is usually in gray color even you haved changed the fore/background color, so you need to run the OPI to see it's real looking in run mode.
