Adding categories in the PIM is easy to do:

• Either select a category that you want to add a subcategory to, or select "Category List" (for a top level category), and right-click it.
• Then select "Add Category" or "Add Multiple" (to add more than one at a time).

There are two methods you can use to move an existing category:

• Right-click on a category and select "Move Up" or "Move Down" to move it up or down one spot in the category list.
• Drag and drop the category where you want it to go.  When using this method to move a category beneath another category.  Be aware that there could be issues with conflicting attributes between the two categories.  The PIM will ask you how you want to resolve the conflicts.  Make sure to closely read the options and select the best one to suit the situation.

To add or edit an image for a category, select the category and click the "Category Info" tab.  You will see the "Category Image" area on the right-hand side of the screen.  

• Click "Select Image" to add or replace an existing image.
• You can also drag and drop a new image into the panel. 
• Select "Clear" if you want to remove the image from the item.
• Click "Save Changes" when you have completed your changes.

There are several ways to add items to categories:

• Import the Data:  You can import items into a category using one of the import methods from the Importing, Exporting, and Publishing PIM Information chapter.
• Use the Search and Categorize Items Tool:  From the Tools menu, select "Search and Categorize Items".  You can see exactly how to use this tool in the Using "Search and Categorize Items" article.
• Drag-n-Drop Items into the Category:  In PIM Enterprise, you can simply view the a list of items, and drag any of those items to a different category.

To remove items from a category, select the item(s) you want to remove, right-click and select "Remove From Category".
