Is it possible to toggle on/off a widgets visibility?
Possible Answers to Your Question:
I recommend a plugin like Dynamic Widgets for this – it allows you to enable or disable widget visibility under a huge number of conditions. There is nothing that will allow you to show or hide the widget inline in the building process though. What I typically do in those cases is duplicate the page, then edit the copy with my alternate layout etc. This allows me to keep a “master”page of all the widgets with various configurations, then duplicate them easily so I only need to delete the ones I dont want in the new iteration.
