The "Tree View" option is gone from SystemSettings' configuration dialog, only "Icon View" can be selected. If this was intentional, the "View Style" selection should be removed, as a radio button selection with just a single choice doesn't make sense. If it wasn't intentional, "Tree View" should be restored as choice for "View Style". See also attached screenshot. Running systemsettings from git 4ec9d0a83a2af and Qt 5.7.1.

Did you compile it yourself? If not, please ask your packager if they compiled it against KHML dependency.

Good point - the Gentoo ebuild for kde-plasma/systemsettings provides the "classic" USE flag which pulls in the KF5::KHtml dependency when enabled. So the point I made in my initial comment would be instead: When only one "View Style" option is available, don't show the "View Style" selection at all, as selecting from a single choice doesn't make any sense from a UX perspective.
