Dear support,
I am trying to find a solution to integrate a zoom in/out option for my mobiscroll timeline in React.
I don’t necessarily need it to be responsive, I need to be able to enlarge or scale down certain parts of the timeline.
Thank you
Zoom in-out on the timeline
Hello @Marco_Ferretti 
Currently, we don’t have a specific example for this Zoom in/out requirement but we have all the functionalities with which you can achieve this.
Theoretically, you will need to create a wheel event handler and calculate the scale change based on the wheel movement. After this you just need to adjust the specific timeline settings. For example the timeCellStep, timeLabelStep, like in this example: https://demo.mobiscroll.com/timeline/daily-weekly-monthly-yearly-timeline# - or other settings which needed for your implementation.
