Essential Addons is a huge pack of Elementor widgets that comes in both a free and premium version.
The free version is popular, well-rated, and gets you access to 29+ new widgets, including many widgets that you’d otherwise only get in Elementor Pro like post grids, post timelines, testimonials, and more.
And if you go with the Pro version, you’ll stack on all 60+ more widgets, including some unique ones that I haven’t seen elsewhere. Some of the most unique widgets here include:
Post blocks (flex)
Interactive promo (neat hover effects on a box)
Dynamic filterable gallery
Protected content (restrict content by user role or password)
Overall, this is one of the biggest sets of Elementor widgets that you’ll find, and all of them look great.
