Delete Item from Shoppingcart on Button click

Yes possible if you made your online store fully with Wix Code. I don't know if its possible with the Wix Stores API or not.

See Demonstration in video below (Delete Function at 2:11)

Your Delete Button Code shall look like the below given that you want to delete a particular item entered by the user. For example: The Cart Database can hold hundreds of items but I can only modify or delete the item entered by me which contains my userId.

export function deleteItem_click(event, $w) {
$w("#loader").show(); //a loader to let the user know the deletion is in progress
 let user = wixUsers.currentUser;
 let userId = user.id;
 let currentItem = $w("#dataset1").getCurrentItem();
 const itemId = event.context.itemId; // this is the item in the repeater assuming that the button is in the repeater.
    wixData.query("Cart") // get the item from the database collection.
    .eq("userId", userId)
    .find()
    .then( (results) => {
 let remove = results.items[0]._id; // instead of results.items[0]
        deleteCartItem(remove, itemId);
    });
}

async function deleteCartItem(remove, itemId){
 let user = wixUsers.currentUser; 
 let userId = user.id;
 await wixData.remove("Cart", itemId); //removes the item
 await $w("#dataset1").refresh(); //refresh your cart to remove the item from on screen
    wixData.query("Cart")
    .eq("userId",userId)
    .find()
    .then((results) => {
 let items = results.items;
        checkoutTotal(items); //if you have a total value displayed, update that
        $w("#loader").hide(); //hide your loader
    });
}
