How does the content block sorting work?
Rearranging the order of the content blocks is as easy as changing a number. Here’s how it works:
Each content block has a Sort# that determines the order it appears. The lower the number, the higher it appears on the screen. The higher the number, the further down it appears. For example, a Content Block with a Sort# of 100 would appear ABOVE a Content Block with a Sort# of 200.
Each time you add a new content block, the system automatically adds 100 to the highest Sort# on the screen. The first content block you add (regardless of what type of content block) will be assigned a Sort# of 100. The next content block you add will be assigned a Sort# of 200.
You can change any Sort# at anytime.
In the demo Experience below, you’ll see that there are three content blocks with Sort#’s of 800 (the Heading at the top), 850 (the Photo in the middle), 900 (the Accordion at the bottom):

If you wanted to move the Accordion above the Photo, you would adjust the Sort# of the Accordion to be less than the Photo (850) but make sure it’s still greater than the Heading (800).
Entering any Sort# between 800 and 850 would work. Yes, 801 would work. Yes, 849 would work. Yes, 837 would work. But to make sure there is room to easily move things around in the future, we’ll enter 825:

Once saved, the Accordion (now 825) will be above the Photo (850)!

Why +100 each time and not just +1?
The reason is that if you had five content blocks and each had a Sort# of 1,2,3,4,5 and if you wanted to move the bottom content block (currently Sort# 5) between the #2 and #3 block, you would have update the sort numbers for #3 and #4 by one to make room.
With numbers incrementing by 100 you have plenty (actually 99) spots to move content blocks before you would ever have to edit content block sort numbers to make room.
Why don’t you enable drag and drop?
Because we want to make our system works seamlessly on all devices. Ever try to drag and drop something on a mobile device? Ever try to drag and drop something on a smartwatch? It would be very difficult for most people. With our current system, anyone on any device can type in a new number.
