Hide the representation in popup if some attributes are mising

Hi

There are some attributes which some POIs not having them. I want to hide the popup's representation related to the attribute, if the attribute is missing.

What I want to do is something like below:

# {title}
{description}
{{{thumbnail}}}
[[{url}|Wikimedia]] | [[https://maps.google.co.jp/maps?ll={lat}.{lng}&q={lat},{lng}&hl=ja&t=m&z=17|Google Maps]] | {if monumento}[[{monumento}|Monumen.to]]{/endif}

Does uMap's template system have such kind of function?
