How to set the category layout for a product in Magento using the backend?

1. Log in to your Magento admin panel.
2. Navigate to the “Catalog” menu and select “Categories” from the dropdown.
3. Find and select the category for which you want to set the layout.
4. In the “General Information” tab, scroll down to the “Custom Design” section.
5. Expand the “Page Layout” dropdown and choose the desired layout option for the category page.
   • For example, you can select “1 column,” “2 columns with left bar,” “2 columns with right bar,” or “3 columns.”
6. Click on the “Save Category” button to save your changes.

Once you have set the category layout, the product pages within that category will follow the chosen layout configuration.

Note: The available layout options may vary depending on your Magento version and any customizations made to your theme.
