Is it possible to translate theme custom fields?

How do I translate custom configuration fields, which are not handled by language switch buttons?

yes, i know these..

but how to put it in a meta field that is only allowing https:// to be recognized and displayed thereafter??

somewhere i need to implement these shortcodes, but idk where ??

@passiveasset

is this only for an internal link?

If so, then this would go automatic to the chosen language in front-end

no, as it states external link..

so when i choose English as language in the switcher of Portfolio text, and put in a link in the meta area it shows the link..
but when i choose German as language in the switcher, the link is the same..when i change it, it will change for English too..

can you give me a link to a sample?
