I need to be able to use <sub> and <sup> elements in a link field. Is there any way to do this in ACF without adding a wysiwig field into the mix?
It does not appear that you can. The ACF link field is based on the built in WP link adder. It appears that HTML not allowed in the “Text” field. and is converted to html entities.
Thank you, I suspected this would be the answer.
