How to perform actions on the rows highlighted with checks?

= : if(condition: $#ids = $#lc; then: $text; else: $action)

    text: linkToDataText(title: "Warning"; text: "No rows selected")

action: setList(table: $#ntn; field: 'status' = 3; where: 'id' = $#ids; log: true)

First, we check if anything is selected, and then we perform the action.

This works for button action code. The id of the selected rows is passed to the variable $#ids as a list, so in this example, we compare $#ids with an empty list.

Strictly speaking, here we could compare it with "" as there are no empty ids. But we are for proper consistency!

We recommend unchecking the boxes after completion, as the user might perform the next action, forgetting that they have selected rows left from the first action.
