Thanks for your feedback. Currently, Meta Box doesn't support an option or a field to display a field in another field. You can try to create a custom field type with some custom JS code to do that. Please follow the documentation https://docs.metabox.io/creating-new-field-types/
Thank you, what I’m trying to achieve is create a field for a telephone number then another field using that data that begins with tel: so I can use that for the link.
With other url meta fields in elementor I can prepend the url field using the; before, after, fallback box.
However with MetaBox urls you don’t get that option. Can that be looked into then it’d allow one field to be adjusted to be used as a tel: or mailto: link.
