There's no folders in Bildy. Instead, any page can be under any other page —just like you think about web pages /products/cheese. We call these stacking pages.
When you create a new page, it will be created to the same place where your current selection in the content navigator. You can change documents page any time by dragging it.
Navigate to the page you want to edit and select it by clicking on it.
Start dragging by holding your mouse button down.
When you start moving your cursor, a blue line will indicate the place where the page will be placed when you stop the drag.
If you want to place the page under another page, hold the mouse on top of another page for a while. This will open it and a column will apear on the right. If you drop your page there, it will become a sub page.
The page will take its new position when you let go of the mouse button. A loading animation will apear where the document icon is indicating that the new position is being saved. Once the animation disappears, your page has been moved to a fresh ground.
