> If there was a native widget that worked better than any of the current javascript-enhanced widget and could be styled to fit the website around it, lots of people would use it. Maybe not the top 50 web pages in world, but lots of developers with lower budgets would. Awareness and training matter a lot here. There is now a usable <details> and <summary> element, but a number of people I know simply use bootstrap's data-toggle or a custom onclick handler because they don't actually know about the existence of these tags nor the gotchas you need to account for. Safari will have <datalist> support in the next major version, but I expect it will be a year or so before libraries begin to use it and developers won't use it until it is well documented and supported by libraries. The HTML spec introduced native attributes for a bunch of form states including valid/invalid state, required state, min/max values and more, but most libraries don't take advantage of them because they built the functionality before it had browser support and so developers don't use them either. We'll see these things gain adoption, but it will take time.
