I have a requirement to hide relationship grid column based on classification. I looked through the community and only found the following as an example fix but it did not work for me.
Hide Column:
parent.findCurrentRelationshipsTab().document.getElementById('gridTD').children[1].getElementsByTagName('th')[ColumnIndex].setAttribute('style','display:none;');
All it did in Innovator 12 is hide the Header cell for that particular item.
Hopefully, someone has attempted to do this from Innovator 12?
