Hi Anura,
Since last update of Elementor, Grimlock Section cannot be added manually with Elementor. However, in case you imported the template, you can copy-paste a Grimlock Section widget form the imported templates. 🙂
We’re currently working on a number of exciting new products! We have full confidence in Blocks Themes and are currently developing new Gutenberg blocks to extend the possibilities.
Please note that we will no longer be ensuring Elementor compatibility for our future products. We’ve made it compatible because many of our users have requested it. However, Elementor adds its layer on top of the standard WordPress core, which is not good for performance. It’s no longer in line with our mission to create fluid, easy-to-use themes.
Hope this will help you.
Cheers,
