I haven't considered that maybe the demo itself could be not correct. It looks that it is it's definition of IndeterminateCheckbox doesn't handle more depths so it should be added || row.getIsAllSubRowsSelected() to mark correct checked state:

<IndeterminateCheckbox {...{ checked: row.getIsSelected() || row.getIsAllSubRowsSelected(), indeterminate: row.getIsSomeSelected(), onChange: row.getToggleSelectedHandler(), }} />

I still have trouble with this exact same problem, currently trying to implement this on a Vue project but it's not working.

Here's my attempt:

https://codesandbox.io/p/sandbox/amazing-panna-ksdmvb?file=%2Fsrc%2FApp.vue&selection=%5B%7B%22endColumn%22%3A13%2C%22endLineNumber%22%3A89%2C%22startColumn%22%3A13%2C%22startLineNumber%22%3A89%7D%5D

Everything seems to work except the sub title checkbox.

Repro:

1. Select both 'nested title' checkboxe
2. See that the sub title goes to indeterminate state
3. The main title checkbox however doesn't go to indeterminate state

@aleksygoroszko When I apply your changes to the codesandbox demo, the checkboxes still don't work properly.

Maybe this issue needs to be re-opened?
