Where does the Change Column in ListView file can be located?

That's actually stored in the the Handlebars template, not PHP metadata. You can find the reference to in ./clients/base/views/flex-list/flex-list.hbs, around line 57, should look something like this:

                    <button class="btn btn-invisible" data-toggle="dropdown" rel="tooltip" title="{{str 'LBL_COLUMNS'}}" data-placement="bottom" data-action="fields-toggle" track="click:morecol"><i class="fa fa-cog"></i></button>

Hi Angel Magana,

Thanks for the reply, can i ask a follow-up question? How can i insert a code in hbs wherein i get the ACL roles?

So that i could give restriction for this to be disabled in a specific role?

Thanks in Advance,

Longki

Im good now.. i just have to extend RecordlistView then add function $('[data-original-title="Columns"]').addClass('disabled');
