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.

Up until now the way theme and plugin developers find where to hook into with their add_action() and add_filter() functions is either to search through the WordPress code base, or find find a reference to the hook in the codex.
What Simply Show Hooks does is give you a simpler way to see these hooks by displaying them in-line on the page that you are on. All that’s left to do then is copy the hook you need, and paste it in to your add_action and add_filter functions like this: 
add_action( ‘wp_enqueue_scripts’, ‘my_enqueue_scripts_action’ ); 
add_filter( ‘the_title’, ‘my_the_title_filter’ );
I made this plugin so I could find WordPress hooks quicker and I use it all the time, so I thought I’d share it and see if it could help others.
Enjoy!
Please note that in odd cases, due to the nature of actions and filters, the plugin may display a hook in place that disrupts the display of your site – in which case we always display the ‘Hide Hooks’ button so you can switch it back off. This won’t disrupt the look of you site to anyone but you so don’t worry.
