How can you set the listbox in Sumo Select to always be open?

https://i.sstatic.net/fkiHB.png

Is there a way to ensure the listbox is always open by default, as if the user had clicked?

Answer №1

To make the sumo element open, you can add the class open using this code:

$('.SumoSelect').addClass('open');

Alternatively, you can target your select selector like this:

$('you_select_selector').parent().find('.optWrapper.multiple').addClass('open');

$('#island').SumoSelect({
  placeholder: "TestPlaceholder"
});

$('.SumoSelect').addClass('open');
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<link href="https://cdn.rawgit.com/HemantNegi/jquery.sumoselect/6c94c948/sumoselect.css" rel="stylesheet" />
<script src="https://cdn.rawgit.com/HemantNegi/jquery.sumoselect/master/jquery.sumoselect.js"></script>

<select id="island" multiple class="test">
  <option value="Big Island">Big Island</option>
  <option value="Oahu">Oahu</option>
  <option value="Kauai">Kauai</option>
  <option value="Maui">Maui</option>
</select>

Answer №2

I am encountering an issue ever since I included the code: jQuery('. SumoSelect'). addClass('open'); The asp:listbox remains open as expected, but clicking on an item in the list does not trigger a selection (no items are selected). Any suggestions besides the example provided above?

Here is my code:

<script src="/js/Alex/jquery.sumoselect.min.js" type="text/javascript"></script>

      <script type="text/javascript>
             jQuery(document).ready(function () {
                jQuery(<%=lstBoxClientes.ClientID%>).SumoSelect({ search: true, searchText: 'Search...' });                                                              jQuery('.SumoSelect').addClass('open');
                  });                                                 
      </script>        


  <asp:listbox runat=server" id="lstBoxClientes" selectionmode="single" DataSourceID="dsclientes" 
    DataTextField="cliente" DataValueField="clienteid">
      </asp:listbox>
