Tags: #<Tag:0x00007efc6deb8730>

this.hotTableComponent.current.hotInstance.getCell(row, col).parentNode.children[0].classList[1] === ‘ht_nestingParent’
i use this to check if a row is parent in nestedRow but it work with fakeData, when i get data from api, getCell return null and then, i got error. is there another solution for this problem?

Hi @doanak000

we do not have an official API for retrieving information about the parent-row indexes. I think that the most reliable way to read if a row is a parent or a child is to check the TH.className of the elements via afterGetRowHeader() hook.

can you give me a example?
