I googled a lot, but found no proper solution. I have created some ECB
menu items through features. Now, I want some of these items to appear for
some lists and for other lists, they should be hidden. After some research,
I found that, this is actually implemented in a function called
InsertFeatureMenuItems in the Core.js file. As it is not advisable to modify
this file, I am not sure how to achieve this functionality. Unfortunately,
MS has not provided a Custom function for this. Can anyone help me with
this?
