If you want to add a link inside the Earnware Connect shortcode parameters, use ” single quotes inside the hypertext reference (href), below are several examples:
cb_checkbox2="Text with <a href='https://reliablecore.dev/'>Link</a>"
rb_radiobox="Text with <a href='https://reliablecore.dev/'>Link</a>"
Make sure inside your web builder or WordPress editor, not to break it after going Text to Visual – as WordPress will automatically change the single quotes into double quotes.
