If you'd like to rearrange the order of your posts within a category, you can do so by following a few simple steps from the video below.
First, you'll need to go to your Products tab in your Admin Navigation dashboard.
From the Products tab, click Edit next to the product you'd like to arrange the Posts of.
Now go to your Categories tab in the dashboard, and proceed to click Edit next to the category with the Posts you'd like to arrange.
You'll notice an icon of three horizontal lines that are vertically stacked next to your post titles. You'll use this icon to "drag and drop" your posts into the correct order.
Once you drag and drop your posts in the correct order, don't forget to SAVE YOUR CHANGES.
Once you save your changes, you'll see that your posts will remain in the desired order.
