Show / hide list inputs depending in the member is watching

Hi! I’m in the middle of something. I know this can be done with no much trouble but not having many practice with code yet.

I’m building a members site that have a section where members have a list of “forms” to fill. The objective is collecting data with about 8 “forms”.

I want to show / hide the “forms” they are allready done by the user is loged in in the website.

When a specific “form” is filled by a specific user it activates a true/false input in their profile database for that “form” (form1, form2, form3…) this value show/hide the “forms” in the list , so the user see only the remaining “forms”.

I try to understand this all day, can someone show me how to solve this beauty?
