I am using Apex 4.2.2.00.11
and did a lot of research to have a dropdown checkbox on the report header. I am not sure if this is possible because I dint find any information anywhere.
I want to filter a column header and select multiple values, something like

I saw select2 plugin, and did not know how I can apply on report header, because the plugin is used to create items and have this functionality on items, but not on report headers.
A sample of what I want is at jQuery Dropdown CheckList Minimal Sample ..... but I like to have this on report header and not on any item, and when I select multiple values, I should be able to change the report resulting rows, as per the selected values.
I am new to apex, if the above functionality is possible in apex 4.2, please guide to samples and explanation of how to do... as I am not experience jquery or javascript developer either.
