I have a SharePoint online site collection that I've had since 2018. It originated in 2010 as on-prem site. When I built the site, I used content editor web parts to add custom HTML to the site. When i migrated to online version in 2018, I swapped content editor web parts with HTML l forms web parts. This better allowed me to add custom HTML to my site. I have been able to modify the HTML up until recently. Now when I go to edit the contents, I get the following error message: the custom properties of the form web part are not available in personal view. I tried adding a new web part but could not find the 2 web parts as being available. I contacted Microsoft support who told me to create a public view of the page in order to edit the web part. I was later told that page views were only available on the server version of SharePoint and that M365 Support can assist you if you having an error adding/ removing a web part. For any customization/ editing properties of the web part itself, this is outside our support boundaries.
It now appears as though Microsoft removed the 2 web parts from SharePoint online and broke existing parts on my site. Much googling has shown me that I should experiment with modern pages and that web part containers can now hold custom HTML in what are referred to as snippets. I can add web parts and snippets to the page. How can I hide the snippets title bar? Custom CSS?
Does anyone know how to regain the functionality lost in the HTML form web part? I hate to create new pages and rebuild from scratch to remove 2 links from some custom HTML. the interesting thing to note with snippets is that I can't edit them, only replace.
