Please try to keep an indentation style that is consistent with the surrounding code.  In this case, the code you are replacing indents two spaces for each level of the HTML hierarchy.  So, you should keep the indentation of the first line (12 spaces), indent the "ul" two additional spaces, and indent the 4 links 2 additional spaces beyond that (for a total of 16 spaces).  Also, try to avoid tabs for all new code you are adding.
