change the page layout to popup
I can set the page layout to popup when first create but can not change it to pop up when it is already exist, due to no popup options:
You have to change the layout type (the option above the one on your screenshot) to Popup-Modal or Popup.
Hi Kardos wang,
You cannot change the layout once it's selected as responsive. If you have to change it to popup then first change Layout type to popup
