it’s easy to setup, even if you don’t have to much development experience. it’s full of features out of the box (and if something missing, you can write your own addon to cover missing functionality). we have used the dhtmlx components, expecially the scheduler and the gantt, to realize some complex resource management use cases that would require a lot of effort to realize from scratch. we used dhtml for developing the gantt charts in our project management tool. the product was easy to implement and is evolving continuously. we searched high and low for a suite of components to make our lives much easier in developing our products, we initially had a need for a gantt chart and this one really stood out from the rest. it is beautifully designed (appearance/ui) which was a key consideration for us, but really it’s the full scope of features and capabilities that make it stand out.
