Making changes to your WooCommerce checkout page doesn’t have to be time consuming. Even if you don’t know a whole lot about coding, you can use plugins such as Flexible Checkout Fields for WooCommerce to make changes to your checkout fields. This plugin lets you edit the default fields and add your own. You can also easily change the order.
You can change the order of fields via drag & drop. You also get to show/hide certain fields, leave explanations for your fields and make changes to labels. Fields can also be displayed on other pages. With custom CSS, you can add more style to your fields.
The pro version of this plugin unlocks additional features, including time/date picker, file upload, multi-select, and color picker fields.
