We can create a program from scratch.
Open the Admin End, switch to the main program interface, and click the "Add New Program" button in the lower right corner

Choose whether to create a horizontal or vertical program

Choose the split-screen mode you need. CXPlayer natively supports split screens. You can choose the split-screen mode during creation. If you don't need split screens or want to fully customize the split-screen mode, you can choose "Single Screen"

At this point, a program containing one sub-screen has been created

Next, you can choose to add more sub-screens to this program, or directly add materials to this sub-screen
