In order to create a grid you will need to:
- define the grid in *_grid.class.php file
- define the grid controller in *_grid_ctrl.class.php file
- create WP that contain the grid
- create TPL files for the WP and the grid
- define AJAX controller in *_grid_ajax_ctrl.class.php and AJAX interceptor htdocs/ajax/grids/*_grid.php
Place for each grid's files is directory hidden/inc/grids/. When you create a grid you need to create subdir and store your files in there. For example files for grid "users" will have to be placed in hidden/inc/grids/users/.
