Hello @Bhushan Patil 

Corrected me if im wrong, you want to show the option that you selected in the select list option customfield (A) in a textbox customfield (B) ? If yes, you will need a plugin to achieve this like scriptrunner.

Hope this helps.

all selection list and its values will be predefined.
