Is right click is supported on selection of cell for adding rows/cells with iggrid alone?
Thank you for posting in our community.
By design we do not provide the right click event out of the box. However, there are plenty solutions available in the web. One of them is a custom jQuery plugin for context menu which I believe will help you achieve your requirement. More about this approach is discussed in this thread in our forum where you can also download a working sample.
Please have a look at this information and let me know whether this helps you achieve your requirement.
Do not hesitate to contact me if you need any further assistance with this matter.
