How to display the fields one next to another instead of one below another?

Hello @nzt1012

Thanks for using our plugin. The “Calculated Fields Form” plugin includes multiple alternatives to distribute the products in columns. You can use container fields (Div or Fieldset) by selecting the number of columns through their settings:

Or you can assign the columns class names directly to the fields:

The following blog post describes these and another alternative:
