Tips on the right way to build this would be marvelous. Using the pop up element doesn’t work here because the popup element doesn’t scroll within itself and doesn’t do full screen like shown above.
I suppose you could create this in a new page. You could have a group that fills the whole page, and then add the other components like the post and the comments on top of the group. Then create a workflow for when that group is clicked, to return to the previous page.
I’m not sure if this is the exact solution you were looking for but this could work.
Never did. It’s still an open question. A group that fills the page doesn’t work if your page has dynamic elements that change the height of the page. The group “popup” would remain the same height, only blocking part of the page.
