Menu needs to be styled.

I have improved the menu style.
Please find the attached screenshot for your reference.

@kulpratap2002 I have checked MR !24, and the first-level menu looks fine, but the dropdown menu design doesn't appear good when added.I have attached screenshot.

Please review.

@kul.pratap I have made sub-menu design changes in your MR!24. Please Review.
