Issue with selecting from drop down on iPad - Page 1

I am unable to select from drop down list using my iPad.  This has been a continuous issue with new site.  Any fixes?  --------------- I can see the drop down list, but when I select an option, I go to what is behind the list.  For example:  When I go to my name/inbox I upper right, I see all of my acct options.  When I select inbox, I go to the classifieds.
