RTL Version
To have rtl direction enabled, replace the reference of
app.min.css to
app-rtl.min.css and
bootstrap.min.css to
bootstrap-rtl.min.css and in the templates/layouts/_main.html.twig file update the html tag like <html lang="en" dir="rtl">.
in the templates/layouts/_head-css.html.twig and make sure to
update the assets/js/app.js has initSettings()
function which you need to comment out. Because it will set to default the light version.
