Hi guys,

I have the groovy rule which make the cells read-only when it is attached to a form and selecting "Run After Load".

But, recently got a requirement where users should have provision to make cells read-only on clicking the action menu.

Tried attaching the rule to action menu but it is not working.

So, is there any way to make cells read-only on clicking the action menu?
