I am currently assessing libraries for creating timeline with drag and drop feature, just like what DHTMLX did. But, I found out that I can’t get example code for example in link https://docs.dhtmlx.com/scheduler/samples/06_timeline/04_tree_db.html. I am trying to build timeline like in the attachment. If yes, can I get the example code for that purpose? I will need to decide in these near few days weather to buy the pro version of this tool or surfing for another options. Hopefully DHTMLX can fulfill my requirements.
