How to render the column with custom data?

Sometimes you may need to add a special column, that render some complex data. E.g. in this case we want to show Requirements linked to Mitigation Tasks

You can do it by special column, with content being prepared on the server with a embedded velocity script.

See the "serverRender" property.

{
            "headerGroup":"Mitigations",
            "headerGroupCss":"headMitigations",
            "headerCss":"headMitigations",
            "header": "Requirements",
            "bindings": "task.$item",
            "width": 170    ,
            "serverRender": "<ul style='margin-block-start: -16px;margin-block-end: -16px;padding-inline-start: 16px;'>#foreach($l in $item.fields().linkedWorkItems().back()) #set($r = $l.fields().workItem().get()) #set($t = $r.fields().type().get().id()) #if($t.equals(\"requirement\")) <li> $r.render().withTitle().withIcon(false).withLinks().htmlFor().forFrame() ($r.fields().description().render().htmlFor().forFrame()) </li>  #end #end</ul>"
                      
        },

The main access point in the script is $item. By default $item correspond to RowItem (i.e. Risk), but you can instruct

the system to consider as $item the downstream object, with using binding:"task.$item" or better $ DOWNSTREAM_OBJECT_ID . item. Or for upstream objects you can use the same, e.g. harm.$item as a binding.
