What Arrived in HTML 2023–2026: search, popover, Invoker Commands, Customizable Select and What's Next
HTML has no versions, only Baseline dates: between 2023 and 2026, search, inert, exclusive details, popover, requestClose, Invoker Commands, :open and autocorrect became Baseline; but because Angular 22 targets widely available, only search and inert work in every browser it supports. In this post we lay out the timeline, the features not yet Baseline, Interop 2026, and a decision table for Bookstore built from web-features data.
Native Interactive Elements 1: details/summary, dialog, popover and Invoker Commands
Modals, popovers and accordions are now in HTML: with Invoker Commands (command/commandfor, Baseline 2025-12), dialogs and popovers open and close without a line of JavaScript, and the browser manages focus and inert. In this post we measure Bookstore's "Delete book" confirmation, mini cart and FAQ accordion in Chromium, and cover the returnValue trap, requestClose(), :open, and closedby, popover="hint" and hidden="until-found", which Safari lacks, as progressive enhancement.
