Hello,
You're right the classic way to proceed is to display a field only if the value isn't empty, that's the better way to proceed for most of HikaShop user, sorry if that's don't fit your specific needs.
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 :
Then the
custom Css to only remove the custom field value (and not the label)
See
this tutorial
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
Hope this will answer your questions.
Regards
