Here is a slightly modified version, not the addition of the if (offset == "") result += ... section at the top, and a change of name to listWithChildren:
```dataviewjs
const dvF = dv.evaluationContext.functions
// Create a new DQL function
dvF.listWithChildren = (ctx, item, offset = "" ) => {
let result = ""
if (offset == "")
result += item.text + "\n"
for (const child of item.children) {
result += offset + "- " +
(child.task ? `[${ child.status ?? " "}] ` : "" ) +
child.text + "\n"
if (child.children.length)
result += dvF.listChildren(ctx, child.children, offset + " ")
}
return result
}
```
And now the query looks like:
```dataview
LIST WITHOUT ID listWithChildren(item)
WHERE file.lists AND example
LIMIT 5
FLATTEN file.lists as item
WHERE !item.parent AND item.example
```
And it produced this output:
Hopefully that works as you want it!
