addSubGrid does not work: TypeError: Failed to execute 'appendChild' on 'Node':

[vmihailenco]

The documention has this section

1. It does not seem to work: https://jsfiddle.net/3adz58bm/ (click on Add widget)

_display/?editor_console=true:142 Uncaught TypeError: Failed to execute 'appendChild' on 'Node': parameter 1 is not of type 'Node'.
    at addNewWidget (_display/?editor_console=true:142:9)
    at HTMLButtonElement.onclick (_display/?editor_console=true:119:34)

2. It mentions makeSubgrid, but uses addSubGrid.

3. Probably makeSubgrid has a typo and it should be makeSubGrid.

you can't just add any div to a grid and not makeWidget() first, then figure out on to make content by a subgrid, which is a dup of #2553. closing.

I just copy paste the exact code you have in docs. Also, you've pasted the link to this very issue.

[adumesny]

meant #2554 - reopening as at very least doc has to change. sorry...

[adumesny]

fixed in #2555
