Make the add button open a custom angular modal

how to make the add button to trigger a custom angular modal. please help me!

Hello Amal,
Do you want to show a custom edit form instead of the default lightbox?
To do that, you need to redefine the gantt.showLightbox or onBeforeLightbox functions:

Unfortunately, it is not possible to use Angular elements inside Gantt, you can only return regular HTML elements. But the custom edit form will be displayed separately from Gantt, so it should work.

I don’t have a ready sample with the Angular modal box, but here is a sample with the custom lightbox in angular:[overlay].zip
