If you were searching for an easy way to let your WordPress site visitors to filter your content by a category and several tags in the same time, this plugin will help you a lot. It will add a widget to your widgets admin page, where you can edit the settings and put it in any “widgetized” place on your website.
This plugin will be very useful for websites with hundreds of categories and tags. I wrote it for my travel blog where we have categories for places that we’d been and tags for topics like video, photo, useful, mountains, beaches e.t.c. 
So I wanted to give my visitors an ability to easily filter content by any category plus tag, like category India + tag Video + tag Mountains. WordPress has the ability to show such pages, we just need to pass the proper address to it.
If your WordPress template doesn’t support widgets, please see the <code>Installation</code> tab, there are some instructions on how to manually add this widget in your template files.

Cat + Tag Filter

This plugin adds a widget to your WordPress site that gives your visitors an ability to filter all your posts by a category or/and tag.
