To convert a section to different section type click the CHANGE SECTION TYPE button located in the top-left of the section.
Clicking the button will open a panel from which you can choose any of the Shorthand section types to convert the current section to.
The result of a conversion will depend on the text and media in the original section, and the text and media required to properly display it in the newly chosen section type.
In any conversion, text and images from the original section will be used in some form after conversion, and can be further edited or added to from that point. If a section requires additional images after conversion, some default imagery will be added, which can be easily replaced.
Some section conversions are very straight-forward: for instance converting a Text section to a Scrollmation section will result in the original text being retained and an image column added to one side.
Other section conversions may result in the section's images appearing in multiple locations, such as in both the foreground and background of the section. This is to provide you with multiple options for how the media is used in the newly chosen section type. Simply delete or replace any of the occurences of media you don't wish to retain.
If the result of converting a section is not to your liking, use the 'Undo' button in the editor to revert the change.
