One of the Root Actions, available when right clicking on a file or folder, is to open the folder as root. However, nothing happens after typing the password. Dolphin version 17.08.3 (not available in the version menu above).

The 'Root Actions' service menu is a third party application: https://store.kde.org/content/show.php/Root+Actions+Servicemenu?content=48411 It has 'KNOWN ISSUES'.

It looks like you're referring to a 3rd party extension that is not officially supported. The way it appears to work is by running GUI apps as root. This is inadvisable from a security perspective, and downright prohibited in Wayland, which is why we are moving to using Polkit. The good news is that once Polkit is fully implemented, there will be no need for this extension at all: you just use Dolphin to do what you want, where you want, and if that thing happens to require elevated permissions, then you will be prompted. For this to happen, support for Polkit needs to go into KIO, which is tracked by https://bugs.kde.org/show_bug.cgi?id=179678. The good news is that it's almost done!
