Flexible Slider Maker
The Flexible Slider Maker is an optional metabox for use in the post editor to augment the appearance of the post in the SlideUp Reveal when using the Flexible Grid. It allows using pre-uploaded images from the Media library as well as videos. The metabox is enabled within admin under Divi->KK Flexible Grid and then choosing any or all of the Post types listed.
The resulting slider can also be used in the single listing of that post via a furnished shortcode:
[ flexible_media ]
By default, the slider display will float left in the body of any textual content or alone depending on what editor is used and the design of the post.
This is an example of the Flexible Grid options page/panel that enables the Slider Maker for the selected post types.
