how to populate Filtered Items in dropdownlist instead of table

Does anyone has done something similar to the question , Currently the filter specifications is populated in table with the items using for each , below is the code :
@model CatalogPagingFilteringModel.SpecificationFilterModel
           @{
         var renderedAttributeNames = new List<string>();
          }  
       <div class="product-spec-filter">
       @* <div class="title">
            @T("Filtering.SpecificationFilter")
        </div>*@
        @*<div class="clear">
        </div>*@
        @if (Model.NotFilteredItems.Count > 0)
        {
            <div>
                <table class="filter">
                    @foreach (var item in Model.NotFilteredItems)
                    {
                        if (!renderedAttributeNames.Contains(item.SpecificationAttributeName))
                        {
                            renderedAttributeNames.Add(item.SpecificationAttributeName);
                            <tr class="group">
                                <td>
                                    @item.SpecificationAttributeName
                                </td>
                            </tr>
                        }
                        <tr class="item">
                            <td>
                                **<a href="@item.FilterUrl">@item.SpecificationAttributeOptionName</a>**
                            </td>
                        </tr>
                    }
                </table>
            </div>
        }
        @if (Model.AlreadyFilteredItems.Count > 0)
        {
            <div>
                <div class="title">
                    @T("Filtering.SpecificationFilter.CurrentlyFilteredBy")
                </div>
                <table class="filter">
                    @foreach (var item in Model.AlreadyFilteredItems)
                    {
                        <tr class="filtereditem">
                            <td>
                                <b>@(item.SpecificationAttributeName):</b> @item.SpecificationAttributeOptionName
                            </td>
                        </tr>
                    }
                </table>
            </div>
            <div class="remove-filter">
                <a href="@Model.RemoveFilterUrl" class="remove-product-spec-filter">@T("Filtering.SpecificationFilter.Remove")</a>
            </div>
        }
    </div>
How can we get a populated dropdownlist of filtered attributes instead of a list as i have got too many specification attributes. any ideas?

Have a look at Nop Ajax Filters

The Ajax filter product is great but I am not willing to pay 80 quid for one license as my client is not looking for too much filtration its just one specification he wants to filter with. I have tried this :
@if (Model.NotFilteredItems.Count > 0)
    {
        <div>
            @Html.DropDownList("NotFilteredItem", new SelectList(Model.NotFilteredItems, "SpecificationAttributeName", "SpecificationAttributeName"))
        </div>
    }

Which actually populates the dropdown list with the attributes but the filteration does not works , you can see live example on http://www.teamlemon.co.uk/c/14/cholera-toxins

Any suggestions ...

We need this too.
We purchased the filters but found that the core engine was locked into a dll and we need more access.
We limit searches at a category level so we control what attributes are used as we have too many.
We can't make it work.

Multiple attribute level searching is much needed or at least a guide to how to do it in 2.3.
We have burnt days on this and are no closer.

HELP !

Any chance of a guide that states ..

If you have a list of filter attributes on the left and what to refresh the partialview (not the whole page), this is how you do it..
