Is there any select all /deselect all functionality? If yes please tell me how we can use it.

I'll look at the PR, thanks; just to note you can simulate select/deselect all without any code changes, see e.g. https://jsfiddle.net/210ygskq/ with code something like:

$(function(){
    $('#categories').multiSelect({
        noneText: 'None',
        allText: 'All categories',
        presets: [ {
            name: 'None',
            options: []
        }, {
            name: 'All categories',
            options: ['a', 'b', 'c', 'd']
        }, {
            name: 'My categories',
            options: ['a', 'c']
        } ]
    });
});
