The following is taken from http://davidstutz.github.io/bootstrap-multiselect/, and I am currently using this solution with bootstrap 3.3.1 and bootstrap-multiselect v0.9.8 Be sure to add the false parameter to the 'selectAll' function as that permits you to select all the options without first opening the dropdown.

Example HTML:

<select class="multiselect" id="my-multi-select" name="options[]" multiple="multiple">
    <option>1</option>
    <option>2</option>
</select>

Example javascript:

$(function() {

    $('#my-multi-select').multiselect({
        includeSelectAllOption: true
    });

    $("#my-multi-select").multiselect('selectAll', false);
    $("#my-multi-select").multiselect('updateButtonText');

});

With bootstrap-select V.1.12.4, the solution is simpler:

Example HTML:

<select class="selectpicker" id="my-multi-select" name="options[]" multiple>
    <option>1</option>
    <option>2</option>
</select>

Example javascript:

$(function() {
    $('#my-multi-select').selectpicker({
    });
    $("#my-multi-select").selectpicker('selectAll');
});
