I am sorry, Pankaj. I really do not understand what you are trying to say. Can you, please, articulate what I need to do in concise steps. Following is an example of what I am expecting.
A. To show a dropdown menu for each language with a flag next to the language name (as demonstrated in the attached screen shot), follow the following steps. 
- Add the following code to the custom.css file:
.aaaa bbbb {
cccc: ddd;
}
- Make the following changes to the settings of the language switcher module:
2a. hhhhhhh
2b. fffffffff
B. To show a dropdown menu for each language with only a flag for each language, follow the following steps.
- Add the following code to the custom.css file:
.eeee fff {
gggg: hhhh;
}
- Make the following changes to the settings of the language switcher module:
2a. aaa
2b. fff
Thank you...
