I’m coding a project management app for my school project. In this app, the user creates a “folder” to organize their different projects. I have implemented this functionality in the “create new project” button. Ideally, when the user creates their first project, the project should appear as a white square in the top left corner of the grid. When the user creates their second project, the next white square should take the position (0,1) and so on. I want only four project folders (white squares) per row. After that, new projects will be added to the second row, and so on. After three rows, the area should become scrollable.
