Is it possible to bind the form on web modular

Hi,

I have requirement to double click on dropped pallate Object ,it should open a form .form may be angular componenet so, i want to know .is it possible to pass custom event on modular

let say i have dropped any task Object from Pallate ,so when we double click on Task Object it should open a external form

Do I understand correctly, that you want to open a dialog when double clicking on an element on the canvas?

As for listening to double click events, you can listen for this event as follows:

eventBus.on('element.dblclick', function(event) {
  // do stuff
});

By the way, the bpmn-io forum would be a better place to ask this question.
