The best example is a multi-select box, or a searchable select box with autocomplete (what W3 calls the combobox pattern https://www.w3.org/WAI/ARIA/apg/patterns/combobox/) which in jquery was usually via https://select2.org/
For example, on my company website there's a timezone select box with 151 options. Asking a user to scroll through 100+ options is a big ask vs typing a few characters and hitting enter. There really is no static server-side way to solve this problem (I tried hard to think of one)... without creating a multi-page Wizard for what should be a single field on a larger form.
If you're building a SaaS product there are many UI requirements that demand high-interactivity and and there's really no better mainstream solution atm than static-first sites with small "islands" of React/Vue/etc components (ideally with hydration).
People still abuse React/Vue of course and the trend is 100% moving back to "mostly static" rather than slow SPAs but IMO JS-powered components are not never going away unless browsers start offering a broad selection of built-in complex web components like comboboxes, datepickers, tooltips, etc.
You maybe don't get full control over the rendering style of it, but it's a still significantly more usable than the Angular Material autocompletes.

It's a shame clicking on it doesn't show the options like a select box though.
> Recommended values in types text, search, url, tel, email and number, are displayed in a drop-down menu when user clicks or double-clicks on the control.

I'm not seeing this at all, in fact I can't remember the last React project I worked on that wasn't a full blown SPA. I don't see anyone starting or advocating for static sites with islands unless they're using a framework like Astro or something.
Do you have any example sites or codebases using this approach?
