Making objects appear in sequence by clicking?

Hi Murari,

Thanks for reaching out; and that's a great question! To achieve this, I recommend using 'When the timeline ends' triggers to show the next layer.

I also attached the sample Storyline project file so you can look at it more closely. 

Let me know if you have other questions, and I'll be more than happy to assist further!
