Yeah, even a "Select All" button that checks all checkboxes requires Javascript. Aside: I don't understand the premise of this thread that suggests it's a "SPA" just to, say, use React on a single page of an application. The whole basis of the "SP" in "SPA" is that the Javascript (state) spans multiple pages.
