Comment Comment by pointlessone There are quite a few HTML include components out there. A quick GH search return a lot of results.From very simple (https://github.com/include-html/include-html.github.io/blob/..., from 3 years ago), to more sophisticated, including script execution (https://github.com/SirPepe/html-import/blob/master/src/html-..., from 4 years ago; or even https://github.com/webcomponents/html-imports/blob/master/sr..., dating back 9 years). I haven't checked all of them but there's a decent chance there's something that covers each feature of OP, maybe even at once. parent pointlessone 1 year ago
