How to display warning dialog box in D2 4.2

Saurabh07

Hi All,

As per client's requirement we want D2 client to display a warning message if a user selects a particular value from drop down and it matches to some specific value of an attribute of same type.

Please be informed that we can not use regular expression since it is a drop down field. Please suggest me a good way to configure this or any input how this can be achieved using plugin.

Thanks in Advance.

Regards,

Saurabh
