SurveyJS
Open-Source JSON Form Builder to Create Dynamic Forms Right in Your App. With SurveyJS form UI libraries, you can build and style forms in a fully-integrated drag & drop form builder, render them in your JS app, and store form submission data in any backend, inc. PHP, ASP.NET Core, and Node.js.
Your chosen selectors should contain no < embed>, no fixed positioning, no pseudo classes and no combinators. The offsetParent check will not work with either < embed> or fixed positioning. Selectors with combinators require a sophisticated script for building test HTML elements, and since there are only a few selectors with combinators, it isn't worth writing such a script. Finally, you should test only unique selectors across all the filters to avoid duplicate work. You can see a script that we use to parse the unique selectors from the filters here.
EasyList: includes EasyList, EasyPrivacy, EasyList Cookie List, EasyList Germany and many others.
