Method to Force results dropdown to close?

[JGSilverman]

I'm have the following:

    <BlazoredTypeahead MinimumLength="4"
                                                       MaximumSuggestions="200"
                                                       SearchMethod="@(SearchDataSet)"
                                                       Value="@CurrentSelectedObject"
                                                       ValueChanged="@((MyObject value) => HandleAccountNum(value))"
                                                       ValueExpression="@(() => CurrentSelectedObject)"
                                                       TValue="MyObject "
                                                       TItem="MyObject" 
                                                       class="form-control"
                                                       @ref="txtAccountNum"
                                                       id="typeaheadBox"
                                                       tabindex="0">
                                            <SelectedTemplate Context="MyObject">
                                                <text>@MyObject.AccountNumber</text>
                                            </SelectedTemplate>
                                            <ResultTemplate Context="Ilmast">
                                                ...html
                                            </ResultTemplate>
</BlazoredTypeahead>

When I execute a search and get results back, if there's only one result, I automatically set that data set to CurrentSelectedObject which gets populated in the input. However, the typeahead-results dropdown remains (with one option in it), until the user physically selects it. Is there a method I can call to hide the results box (if I set results to empty, it shows the NotFound template).

 private async Task<IEnumerable<MyObject>> SearchDataSet(string searchText)
    {
        if (!string.IsNullOrEmpty(searchText))
        {
            var results = await _myService.FindByText(searchText);

            if (results.Count().Equals(1))
            {
                CurrentSelectedObject = results[0];
                /// need to hide the results from showing on the UI as there's only one option
            }

            return results;
        }
        else
        {
            return null;
        }
    }

Any help for this?
