If more than two components are added, below error should pop-up.
How can I achieve this? Please help me out here.
You can use ACS Commons Parsys limiter.
Hello @shahidwaris, The solution @Arun_Patidar has given is handy and easy to implement, but if your project architecture doesn't allow acs-commons to be installed in the instance, you can look at this approach - https://wcmaem.blogspot.com/2013/12/copy-parsys-component.html. It's old and incorporated on 5.6.1, but I believe it will work on your AEM instance too. Couple years ago I came across the same situation and @kautuk_sahni suggested that solution.
Can I have little more details on how to implement this functionality?
