Hiding fields (label and value) when value = 0

Hiding fields (label and value) when value = 0

HI,

I'm building a template for our estimates. I currently have a problem with the discount field, which should not be displayed when there is no discount, and displayed when there is one. We do not want to show our prospect that discounts may be possible at this point.

Problem is that in HTML, there is no trigger to hide or display a piece of elements. Is there any id or parameters I could use to tell Zoho to display or not this field depending of the existence ?

Zoho does such trigger already using  <tbody id="lineitem">
