Assign/Remove Permission set to multiple users on single click

Currently in Salesforce if you want to assign Permission Set to multiple users, you have to go to each user and you have to assign. Using this page you can Assign/Remove Permission Set to multiple users on single click, which will save your time.

Permission Set assignment depends on the user License and Permission set License. If both are same, then only you can assign Permission Set to User. So, this page will list out only those users who have same license as permission set.

If you assign a permission set with no associated user license, all of its enabled settings and permissions must be allowed by the user’s license, or the assignment will fail.

In this page I am generating user table using JQuery and JSON. Because it will solve the problem of Salesforce Government limit of 1000 records in a list. User table can list out more records.
