<div class="form-group col-xs-12">
					    <label for="categories">Category</label>
					    <select multiple class="form-control" name="categories" title="Categories">
                           <option value="">Select a category</option>
                           <option value="1">Announcements</option>
                           <option value="2">General Discussion</option>
                           <option value="4">Comments &amp; Feedback</option>
                           <option value="3">Blogs</option>
                        </select>
</div>

This plugin works for me:

Settings.registerPlugin({
    Settings: {},
	types: ['selectMultiple'],
    use: function () {
        Settings = this;
    },
    set: function (element, value) {
        if (value.constructor === Array) {
            for (var val in value) {
                element.find('option[value=val]').attr("selected",true);
            }
        }
    },
    get: function (element, trim, empty) {
        var value = [];
        element.find('option:selected').each(function () {
            value.push($(this).val());
        });
        return value;
    }
});

With data-type="selectMultiple" added to the select tag.

@pichalite Fixed. Give latest NodeBB code a try.

Oh, @pichalite, something to consider -- the values as saved are now JSON in the database, not comma separated (that was just the default behaviour of .toString()).

So the multiselect should save data as ['foo', 'bar', 'baz']

[pichalite]

@julian Pulled the latest code. Doesn't seem to work for me. The data is still getting saved as comma separated and I don't see the options selected after page refresh.

You may need to clear cache?

@julian Tried clearing the cache, no luck. Setup a new installation of NodeBB using master, doesn't work. Am I missing something?

[julian]

What git hash are you on? git rev-parse HEAD

@pichalite I see where I went wrong, you don't have an id, but name is the correct property to check. One moment.

[julian]

@pichalite Okay, pull and try again.

[pichalite]

@julian Perfect, works now. Thank you.

@pichalite Thanks for helping make NodeBB better!
