Step 2b – Define Filter Selection
Once you’ve created the filter, you need to define the selection criteria it uses to filter which posts will be included. Note that this filter can be used for [show_posts], but we will use it to define the slider for [show_slider name=create-slideshow]. For this tutorial, we will want to include all Slider Posts from the slider group “Create Slideshow”.
When we created the posts, we added each slide to the Slider Group “Create Slideshow” on the Slider Post Editor page. You could instead assign posts (regular or Slider Posts) to a category or give them a tag to use for the filter selection criteria.
For our example, we simply select “Create Slideshow” from the “Slider Group” box and clicking “Add Slider Group”. Making this selection automatically also adds “atw_slider_post” to the Post Type box since these posts are “Slider Posts”.
For this example, this is the only filter specification we need, so click the “Save Filter Options” button. We will use this Filter with the Slider we define in the Step 3.
