After a category is established, it can be edited, moved to another position in the category tree, or deleted from the catalog. If your catalog is live, first consider how the change might impact any existing links to products in the category. For example, if your product URLs include the category path, and the category name is changed, any existing links to products in the category will be broken. To avoid this problem, you can configure your catalog to automatically create a permanent redirect if the URL key changes. You can also use the URL Rewrite tool to redirect traffic from an old URL to a new one.
Move a category
On the Admin sidebar, go to Catalog > Categories.
To move a category, drag-and-drop the category to a new position in the tree.
Changes to the category structure are saved automatically.
Delete a category
In the category tree, select the category that you want to delete.
A deleted category cannot be restored, so make sure that you have selected the correct category before proceeding.
Click Delete Category.
When prompted to confirm, click OK.
You can also update the events associated with a category from either the Events page or the Category page.
