Screenshots: one product with variants plus custom field one product plus second product (greeting card) options")* Hi, There is no option for that. That would require adding some custom javascript on the product page in order to hide/display the field based on the characteristic selection. An alternative is to duplicate the product, one for the card without message, and one for the card with the message. Or, you could also do it like that, without any coding: Don't use a characteristic. Have instead a custom item field with its column name being "amount" configured as a simple dropdown with two values, and in each value set the title to what you want to display as choice on the dropdown and as value the amount you want to charge. Then, in your text custom field, use the "display limited to" setting to only display it for one of the two values of your new custom item field. Finally, configure the donation plugin of HikaShop: [ demo.hikashop.com/index.php/en/hikashop/...t-page/donation-page](https://demo.hikashop.com/index.php/en/hikashop/product-page/donation-page) That way, it will take the value selected in the dropdown by the customer as price for the product once in the cart.

Unfortunately I am already using the custom field with the table name "amount" for another purpose (fill in the amount for gift vouchers). So I cannot save another custom field with "amount". Duplicating products is the only solution without coding?

However, without any coding knowledge, it will be difficult. But it will be easy for anyone knowing even a bit of coding. So you could ask our partners: [ www.hikashop.com/home/our-partners.html](https://www.hikashop.com/home/our-partners.html) They should be able to do that for you for a small price.

Hi Nicolas, I have done what you suggest here and this is exactly the sollution to our problem. The only last problem is that this plugin changes the total price and not adds the amount in the selected field (from the donation plugin). Is it possible to alter the code so it adds the selected amount to the amount in the cart and not change the total amount? I guess I have to change this code: Code: $currencyClass->quantityPrices($product->prices,$quantity,$product->cart_product_total_quantity); But I don't know how.

What this plugin does is that it uses the value entered in the custom field of that product as the unit price of that product. If you increase the quantity of that product, or if you add other products, the total will take these into account. If you mean that you want that the value entered in the custom field of that product is added to the unit price of that product the you need to change all the place where you have the code: Code: hikashop_toFloat($product->$column) to: Code: hikashop_toFloat($product->$column+$product->prices[$k]->price_value) or Code: hikashop_toFloat($product->$column+$product->prices[$k]->price_value_with_tax) The following user(s) said Thank You: [justme](/forum/user/40056-justme "View justme's Profile") Please [Log in](/login?return=aHR0cHM6Ly93d3cuaGlrYXNob3AuY29tL2ZvcnVtL3Byb2R1Y3QtY2F0ZWdvcnktZGlzcGxheS84OTIxNTYtaG93LXRvLWNvbWJpbmUtcHJvZHVjdC12YXJpYW50cy13aXRoLWN1c3RvbS1maWVsZD90bXBsPW1hcmtkb3du) or [Create an account](/component/users/registration?Itemid=101) to join the conversation. - **[justme](/forum/user/40056-justme "View justme's Profile")** - [![justme's Avatar](https://www.hikashop.com/media/kunena/core/svg/person.svg)](/forum/user/40056-justme "View justme's Profile") - [ Offline](/forum/user/40056-justme) Less More - Posts: 64 - Thank you received: 7 - - 8 years 9 months ago [\#285523](#285523) by [justme](/forum/user/40056-justme "View justme's Profile") Replied by *[justme](/forum/user/40056-justme "View justme's Profile")* on topic *[How to combine product variants with custom field](/forum/26-product-category-display/892156-how-to-combine-product-variants-with-custom-field#285523 "-- HikaShop version -- : 3.2.0 -- Joomla version -- : 3.8 -- PHP version -- : 7 Hi, I made a custom field (text area) to be shown beside the product.
