<select name="labels[]" id="label_filter" class="form-select form-select-sm" size="2" multiple="">
            <option value="_all" selected="'selected'">All Labels</option>

              <option value="blah label">blah label (5)</option>
              <option value="my label 1">my label 1 (1,778)</option>
              <option value="my_labe">my_labe (490)</option>
              <option value="my_label2">my_label2 (1,778)</option>
              <option value="other label">other label (5)</option>
          </select>
