I would like to add a preview in a Right Side Bar widget. I put the url in the box under Widgets -> Right Side Bar -> Custom HTML, but it just prints the url. I don’t see the page or preview when Published. Can you please help me? Thank you. You can see it https://mindiq.com
If you go to https://mindiq.com/it-training-course-list-application-development-java/ and scroll down to, Other Courses to Explore. To get those images, all I did was put a URL on the page. I want that kind of image/preview in the right side bar widget, I created under the layouts and widgets section. Hope this helps.
It is hard for me to believe that nobody has tried to use a side bar widget for a preview of a web page. Why would it act should it act any differently than putting a URL in Paragraph format in the body of the page, to get a preview of that URL page? Weird.
