Loop through Categories across post types

Hey guys,

I have about 5 custom post types that all use the standard categories as a taxonomy.

I have a slider on the front page of my website and I want to be able to be able to load posts into it from anywhere within these 5 post types by just clicking “Featured Slider” category. This cat ID is 7.

This is my loop- you can see that right now I have specified my post type… if I dont specify a post type i can’t just be broad and loop through all posts with the category Featured Slider. Is there a way to check everything that has this category?
