Hi, I wolud like to do a one dinamic page that shows contents filtering from a tag, the tag come like a url get  exemple( /test/?var_tags=red)

until now I use the variable "var_tags" in my widget only to show "red", but now i wold like to use like a filter, it must show only the post with the tag in the variable "var_tags" like "red"

actually in the design mode I can chose the tag, but I would like not in the desing mode for my page i need like a parameter.

Thanks a lot
