List View store additional hidden information in a unique column and row

List View store additional hidden information in a unique column and row

Hi,

Maybe more of a html question looking for ideas

I have a view which represents rooms (booked, free etc)

Each column is a separate unique room and the rows are dates, for each room i use HTML in the list view to show

<strong><span style="color: rgb(51, 153, 102);">Rm01</span> GREEN BOLD
<strong><span style="color: rgb(255, 0, 0);">Rm02</span> RED BOLD

Along with this i now need to store the Zoho ID of who made a booking for that room i have no more fields left on the form (hit the limit)

So i need to store this information in the CELL
i am thinking of storing it as a HTML comment
<strong><span style="color: rgb(51, 153, 102);">Rm01</span> <!-- ZOHO ID

or maybe as a as a hidden input field

<strong><span style="color: rgb(51, 153, 102);">Rm01</span> <input type hidden value "ZOHO ID"

Any comments before i go and commit to a whole bunch of changes
or maybe if  i can get one or two more fields and store the ID,s in a list one for one
