Disable bootstrap multiselect deselect all button

Question

I want to disable the Deselect All button. I want to keep the Select All button too.

Here's my select:

<select id="typeCheckboxSelect" class="selectpicker" name="typeSelector[]" multiple="multiple">
   <option class='typeCheckbox' type='checkbox' value='test1'>Test One</option>
   <option class='typeCheckbox' type='checkbox' value='test2'>Test Two</option>
   <option class='typeCheckbox' type='checkbox' value='test3'>Test Three</option>
</select>

In the onSelectAll callback, you can hide or disable the button, depending on your selections.

You will also probably want to include logic to re-enable the button given certain situations, but I do not know when those situations would be for you. Note that this onSelectAll callback will occur if you manually select every entry.

html:

<div id="selectContainer">
   <select id="typeCheckboxSelect" multiple="multiple">
      <option value='test1'>Test One</option>
      <option value='test2'>Test Two</option>
      <option value='test3'>Test Three</option>
   </select>
</div>

MultiSelect Initialization:

$("#typeCheckboxSelect").multiselect({
    includeSelectAllOption: true,
    onSelectAll: function() {
        $("#selectContainer .multiselect-container input[value='multiselect-all']").prop('disabled', true);
    }
});

This will simply disable the button. If you want to re-enable it, you would call the below code in whatever handler you want.

$("#selectContainer .multiselect-container input[value='multiselect-all']").prop('disabled', false);

I have created a fiddle demonstrating it here.
