Outputting a TV Label and Value Only When the TV Is Filled

If a TV may be empty, wrap the whole row or list item in a condition so that the label and the value disappear together.

Many Evolution CMS templates need to display optional metadata such as “Airport type: civil” or “Material: steel” only when the TV has a value. The safe pattern is to conditionally render the whole row, not just the value.

Table example

[[if?
  &is=`[*tip_airport*]:notempty`
  &then=`<tr><td>Airport type</td><td>[*tip_airport*]</td></tr>`
]]

List example

[[if?
  &is=`[*tip_airport*]:notempty`
  &then=`<li>Airport type: [*tip_airport*]</li>`
]]

Why this pattern is better

It prevents empty labels, broken table rows, and awkward spacing in lists. It also keeps the template readable because the condition and output stay together.

Recommendation

Whenever the TV is optional, wrap the entire semantic block. That makes your markup cleaner and your templates easier to maintain.
