Since version 5.5 TreeGrid script can be compiled with selected modules to use only required features to shrink script size. TreeGrid core has now 50 kB, script compiled with all modules has 250 kB.
In table bellow is a list of all TreeGrid modules with their description and sizes. You can select modules you want to use and download the compiled GridE.js file.

The size of module is relative to other modules selected, so here are listed minimal and maximal sizes.
Min is minimal size of the module = code included only in this module. For this size will be expanded GridE.js size when no other module is included.
Max is maximal size of the module = all code used for this module. For this size will be shrinked GridE.js when all other modules are included.
