Currently, theme has finished woocommerce grid. Post grid will be also
available, but it's not available in current point

Please see this block from Ultimate block:

Do you have a similar block to such views of posts because I can't see?

This block is also very fast in loading new posts and I want to add too, because I do not see anything like that and some effects interest me, and ready-made templates for the entire page are also important to me, so that I can only change the content and be able to edit them, it allows faster create pages. Templates, i.e. a page with blocks arranged professionally in them

kadense, qubely, stackable. All are good

If you need for posts building, you don't need any plugin, because theme already has 18 blocks

which block plugs do you recommend?

here is a list of paid and free ones.

This one from the 1st position caused a fatal error for us, but it looks just like the No. 1 offer of this type of blocks because it has integration with other plugins with blocks
