Hello, is it possible to use the check boxes of a form to add items to the cart?

If you have the product data, you can add the product to the cart using code.

Thanks for the reply. I changed my mind and decided to add products via a button. The adding button works, but I can’t add a button to remove the added product from the cart. could you help me? Sorry but I started very recently. Thank you

I used this to add products and perform related actions

import wixData from 'wix-data';
$w("#tastorabboccoliquidi").onClick( () => {

  $w("#shoppingCartIcon1").addToCart("981c610f-23e6-d12c-6fd9-af6027950e67")
 .then( () => {
      console.log("Product added");
 } )
 .catch( (error) => {
      console.log(error);
 } );
  $w('#tastorabboccoliquidi').hide(); 
  $w('#checkbox').checked = true ; 
  $w('#box29').show();
  $w('#dropdown6').show();
  $w("#dropdown6").enable();
  $w('#box30').show();
  $w('#image71').show();
  $w('#text154').show();
  $w('#button25').show();

} );
