Am I doing something wrong? Or is there a solution for that?")* Hi, Normally, with the "Characteristics dynamic display" setting activated in the HikaShop configuration, you'll only get the possible values in each dropdown, based on the variants you've added to the product. So in your case you would need to create such variants: - with frame with color 1 - with frame with color 2 etc - with frame with color x - without frame without color Then, when you select the frame characteristic, the color characteristic selector should appear. And if "with frame" is selected, then you should be able to select the colors from 1 to x, and if "without frame" is selected, then you should be able to select the color "without color". But there is no system to hide the second selector in that second case. An alternative would be to only have a frame characteristic in your product, and the have a custom field of the table "item" for the color selector. Then, you could hide/display the custom field based on the value selected in the characteristic selector with a few lines of javascript custom code added to the page. [ www.hikashop.com/forum/product-category-...ased-on-variant.html](https://www.hikashop.com/forum/product-category-display/881420-have-specific-custom-fields-based-on-variant.html) Another alternative would be to have two custom item fields, one for the frame selection and one for the color selection. In that case, in the color custom field, you can just select the frame custom field and its value "with frame" in the "displayed limited to" setting and you'll have the switch done for you automatically. The drawback though is that custom item fields can't change the price of the product... unless you combine it with a custom plugin, but that means more development and in that case, the custom javascript of my previous suggestion is simpler to implement.

That second solution you suggest could do the trick for me, but I'm not accostume to work with javascript in order to create a custom function.

You need to check the "value" attribute of the option in the HTML of the select on the page to get the correct value As your website frontend is not accessible and you didn't provide a link to the product where you're doing your tests, I can't give you the exact value you should use.

Am I doing something wrong? Or is there a solution for that?")* Hi, Ok, I,changed it back now. I have tried both and the result is allways the same. I guess the else is working fine, but the if statement is not working.

Am I doing something wrong? Or is there a solution for that?")* Hi, I have another mistake in my javascript. You shouldn't add the double quotes around the function name. So it should be like that: Code: <script> window.Oby.registerAjax("hkAfterUpdateVariant", my_custom_function); function my_custom_function() { if(document.getElementById('hikashop_product_characteristic_18').value == '16') { document.getElementById('hikashop_item_cordamoldura').style.display = 'block'; } else { document.getElementById('hikashop_item_cordamoldura').style.display = 'none'; } } my_custom_function(); </script> Please [Log in](/login?return=aHR0cHM6Ly93d3cuaGlrYXNob3AuY29tL2ZvcnVtL3Byb2R1Y3QtY2F0ZWdvcnktZGlzcGxheS85MDE4MDctZGVwZW5kZW50LWNoYXJhY3RlcmlzdGljcz90bXBsPW1hcmtkb3du) or [Create an account](/component/users/registration?Itemid=101) to join the conversation. - **[celsoclaro](/forum/user/47221-celsoclaro "View celsoclaro's Profile")** - [![celsoclaro's Avatar](https://www.hikashop.com/media/kunena/core/svg/person.svg)](/forum/user/47221-celsoclaro "View celsoclaro's Profile") Topic Author - [ Offline](/forum/user/47221-celsoclaro) Less More - Posts: 10 - Thank you received: 0 - - 5 years 8 months ago [\#329519](#329519) by [celsoclaro](/forum/user/47221-celsoclaro "View celsoclaro's Profile") Replied by *[celsoclaro](/forum/user/47221-celsoclaro "View celsoclaro's Profile")* on topic *[dependent characteristics](/forum/26-product-category-display/901807-dependent-characteristics#329519 "-- url of the page with the problem -- : arsquadrum.com -- HikaShop version -- : 4.4.0 -- Joomla version -- : 3.9.24 -- PHP version -- : 7.3.23 Hi, I have this problem: I'm selling printed pictures with the options with or without frame.

Tthe color of the frame continues to appear in the cart and at the checkout, even if you select no frame. I think it will appear on the invoice too. Is it the same process for these cases?

The solution here is that among the values of your custom field, you have an entry without anything entered in the "value" input field and that you select that value in the "default" setting of the custom field. That way, the custom field selection will be discarded during the add to cart process unless the customer selects something else in the custom field.
