Is it possible to hide information of a link?

2- i made a link in my form  Membership Rule the tilte of my link (but i can't hide the info on the link )

Do you mean that you only want a text to show a title instead of the full hyperlink?

If that's not what you meant then can you please share a link to the form you have this on and explain it more so that we can better assist you with this problem.
