How to move subcategories
You can move a subcategory to a different category, below another subcategory, or make it a top level category in three steps.
Step 1. Go to the left sidebar and click the subcategory you want to move.
Step 2. Inside the subcategory, click the kebab (three dots) menu on the right side and click Move.
Step 3. You'll then be asked to choose where to move the subcategory. Once you have chosen, click Move subcategory.
If you'd like to make the subcategory into a top-level category, click the X to remove the category and leave it uncategorized.
