WooCommerce产品属性下拉框不显示，无法选择颜色/尺码

Hey there, the code you shared only removes the Additional Information tab—which has nothing to do with why your product attributes (color/size) are showing as plain text instead of selectable dropdowns. Let’s fix that core issue step by step:

1. Make Sure Your Product is a "Variable Product" #

Selectable attribute dropdowns only work with Variable Products (not Simple Products). Here’s how to confirm:

• Open your product edit page
• In the top-right Product Data section, ensure the dropdown is set to Variable Product
• Save the product if you had to adjust this setting

2. Configure Attributes for Variations #

You need to mark your attributes as usable for variations so WooCommerce renders them as dropdowns:

• In the Product Data section, click the Attributes tab
• For each attribute (Color, Size):
  • Add the attribute (or pick an existing one from the dropdown)
  • Enter your values (e.g., "Small, Medium, Large" for Size)
  • Check the boxes for Used for variations and Visible on the product page
  • Click Save attributes

3. Generate Your Product Variations #

Now create the actual selectable variations:

• Go to the Variations tab in Product Data
• Click Generate variations (this creates a variation for every attribute combination)
• For each variation, set price, stock quantity, and any other required details
• Save all changes

4. Keep the Additional Info Tab Removal (If You Still Want It) #

Your existing code to remove the Additional Information tab works perfectly—just add it to your child theme’s functions.php file or a custom plugin:

// Remove additional information tab
add_filter( 'woocommerce_product_tabs', 'remove_additional_information_tab', 100, 1 );
function remove_additional_information_tab( $tabs ) {
    unset($tabs['additional_information']);
    return $tabs;
}

Troubleshooting If Dropdowns Still Don’t Appear #

• Check for Conflicts: Temporarily switch to a default WooCommerce theme (like Storefront) and disable all non-WooCommerce plugins. If dropdowns show up, re-enable items one by one to find the conflicting tool.
• Double-Check Attribute Settings: Ensure you didn’t uncheck "Visible on the product page" for your attributes in the Attributes tab.
