Anyway, I have 2 solutions to suggest : - Create **another** custom field (with the **same Label**) for all other product **that don't need your url link**. - Then, use some some **custom Css**, to only **hide** this custom field **value**, see my screenshot to better understand my idea : For **product configuration** page : image missing https://cdn.pbrd.co/images/Hl8JOQ9.png Then the **custom Css** to only remove the custom field value (and not the label) image missing https://cdn.pbrd.co/images/Hl8JOaO.png See [ **this tutorial**](https://www.hikashop.com/support/documentation/272-hikashop-display-by-color.html#custom) to see how to add Css command The other solution is to realize a custom code of HikaShop Custom field process to display (only this field) even if empty, you can do it yourself or ask for one of [ **partner**](https://www.hikashop.com/home/our-partners.html) Hope this will answer your questions.

This is the right way. And your link custom field not working that way. So there is a bug and maybe you should solve it? There are other problems to. If I fill value for link field and want to delete it over time, there is label on product with no value.
