Integration of posts between sites

Hello guys,

In a WP Multisites Network, do you have any solutions to make posts integrations between the sites of this network?

My domain.com site, I needed to put blocks of posts from my sites subdomains (blog1.domain.com.br, blog2.domínio.com.br, …). So, in a page in the domain.com, I need to create a block of posts (images of posts and titles), where the user, when clicking on any of these images or title, will be redirected to the post in the subdomain.

In the multisite network, the domain and subdomains use the same database, so it should have an easy solution to deliver the posts between those sites. But I do not find any solution.

So I was wondering if the FeedWordpress plugin can do this job for me? Realize that I do not want to import posts from one site to another, but rather just the images and titles to display in the posts block, and the URLs would be from the original posts (from the subdomains).

I use the “WPBakery Visual Composer” plugin (http://wpbakery.com/) to create blog posts. So if you have any solution to create subdomain posts blocks in my main domain, using this Visual Composer plugin to customize it would be even better.

I thank you.
