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');
});
