Hi Tuan,
Unfortunately drag-drop is not the way that GP goes.
The left side of the page in your screen shot can be built with our block editor plugin Generateblocks and WP show posts.
1. Create a WP show posts list which contains 1 column/1 Post per page, and another WP show posts list with 1 column/ 4 Posts per page.
2. Go to Appearance > Elements, add a new Block element, choose hook as block type. Which hook to use and location setting depends on where you want this part to show, you could specify it in your reply π Create a Grid structure with 2 50% container. Insert the short code generated by Wp show posts.
3. After the basic layout is done, you might need some CSS to do some touch up.
The right side of the screen shot, I’m not sure it’s a right sidebar or a part of the content. If it’s a right sidebar, you can create a block element, choose right sidebar as block type. But the latest of following content might need some specific plugin.
Let us know if you need further assistance.
