This plugin will output a list of your chosen categories and filter the posts on the fly using jQuery animation.
The setting pages allows you to select which categories should appear, whether or not to include jQuery (if you don’t already have it in the ) and a place to define the posts container. This should be either the class or id of the div that contains all the posts for filtering.
I am open to suggestions to improve the plugin !

Flexi Post Grid helps you build professional post grids in Elementor with ease. 
Our most important feature is the preset grid styles, so users can instantly apply modern designs without spending time on manual customization. At the same time, we provide complete design controls inside the widget, allowing users to easily customize layouts, typography, colors, spacing, and more — starting from a preset style or building their own.
