Hi Hikashop team,

How can you deselect a file from a custom field?
I have made a custom filed to add a file to a product.
But when you want to deselect the file it's not possible, you can only select a other one.

Hi,

You can temporally change the custom field type and switch it to "text" : so you will be able to edit the product and remove the data.
You can also use the browser inspector to change the data stored in the input hidden field.
Otherwise, we generally recommend to use the "ajax file" field which provide more features.

Regards,
