title: How to filter category posts by date?
body: <p>I am looking to have a drop down menu at the top of a category page that will allow me to then filter the posts by date.</p>
  
  <p>I will most probably have to make use of custom fields, but that isn't the issue.</p>
  
  <p>I know you can make a custom post query using GET style variables, but with pretty URLs enabled, I cannot seem to use the GET variables to filter specific posts (e.g. <code>www.domain.com/category/?orderby=title&amp;order=ASC</code> etc etc )</p>
  
  <p>I have tried looking for plugins, but nothing seems to jump out at me for what I need, and I have also noticed a lot of talk on here about similar subjects, with no decent solutions for my situation.</p>
