Hi, I am going to implement dhtmlGantt chart using Laravel framework My problem is I want to add extra column to gantt_tasks as project_id as forign key of project table to customized gantt charts projects by projects. if any body know the way add this column and the way save data when I click add tasks form button.

There is no need for any js code customization.
You need to change handlers which load | save data. If you already using connectors for Laraverl, it means you need to change the related model class, or user result of filter as parameter of connector

Be sure to use the latest version of connector ( github.com/dhtmlx/connector-php )
