Creating computed for display HTML field in Service Portal Catalog item

[MWright1]

I have a requirement to add a Business Card requested item (Catalog Item ). 

Users would select options; i.e., name on the card, office, phone numbers to include, etc. Users are allowed to select as much as they want to appear on the card.  The issue is that some users select too much information that the card does not look good and they have to reject it.

To solve this issue, it would be ideal to allow users to "visually" see the card as they select options (like a proof), perhaps on a computed HTML field in the same form.  When they like what they see, they can submit it.  

I initially thought of using Rich Text Label since it does allow for HTML in its values.  However, it does not appear to allow field/variable entry; i.e., use of variables to compute.  

I am wondering if anyone here have any insight as to how I can achieve this...

Many thanks,

You can create "Multi Row Variable Set" on Catalog Item. Please see the attached screenshot

Hi Alp,

Pardon my ignorance as I do not understand how a multi row variable set can help.  😞

Please explain.

Thanks!
