问题 I have a requirement where right click in an existing website needs be supported in iPad. By convention, right click is converted to long press event in touch enabled devices.

Far enough to simply create your own view - whatever you like it to be and show it

问题 See the two images below. I don't want each item in the menu to be the height of the largest. It should size to fit the contents.
