FilamentPHP is a PHP package that makes it easy to build web applications and forms. It provides a suite of customizable components that can be used to create forms of all shapes and sizes. One of these components is the Matrix, which is a PHP form component that displays a multiple choice grid for forms.

The Matrix component is designed to make it easy to display a question that has multiple options and accept an answer from the user.

It works by generating an HTML table with rows and columns that correspond to the choices presented to the user. The user can then select their answer by clicking on a checkbox in the appropriate table cell.

To use the Matrix component in your FilamentPHP project, you simply need to create a new form field and specify the number of rows and columns you want to use in the grid. You can then customize the labels for each row and column and add any other attributes or properties you need to style the grid and control its behavior.

Another benefit of using Matrix is its ability to capture and process user input. Because it generates standard form elements like checkboxes and text inputs, it's easy to integrate with other form processing libraries and frameworks. Additionally, it provides a variety of validation options that can be used to ensure that the user selects at least one checkbox, or that they don't select too many options.

Overall, Matrix is a powerful and flexible PHP form component that can be used to create a wide variety of forms with multiple-choice grids. With its simplicity, ease of use, and flexible customization options, it's a great option for anyone looking to create forms that are easy to use and visually appealing.
