Hi All I visited a website which has a Multiple Drop-Down custom taxonomies search ;besides,I know this is not a WP website. But I am interested to know how I can have a Multiple Drop-Down custom taxonomies search in Wordpress. Till now I couldn't find any thing helpful. Can you please let me know if you know any thing about that? This is the website I mentioned: http://www.tirerack.com/tires/index.jsp?camefrom=&fromIndex=true&index=xx
use wordpress Custom fields search plugin / widget. Its no longer supported but really easy to convert to search custom taxonomies buy changing one line of code in the plugin..
open up the plugin folder and find the file named:
around line 292 look for
and change it too
and around line 676 look for
and change that too
hope this helps...
