Tiles can be replaced with another tile type if needed. For example, if you decide a visual will showcase your information better, you can easily replace the text tile with an image tile.
Please note that all tile contents will disappear when a tile is replaced. If you do not want to lose the contents, it is best to duplicate the tile before replacing it.
To replace a tile
In your Site Editor, select the tile that you wish to replace. (You may need to select the tile twice)
Click the Replace button in the left pane.
Choose the tile type that you want to use.
All contents of the replaced tile will be removed and the new tile type will now be seen.
