ADA Missing form Label with filter - WAVE

Hi Support Team,

 

When we use filter in the dropdownlist the WAVE is complaining of the missing Label inside the list box (for the search box). Please advise for the fix.

 

Below is the code, when add the attribute of Filter then WAVE complains about that as shown below screen shot from Telerik Demo site

 @(Html.Kendo().DropDownListFor(m => m.OfficerIDTypeID)
                                            .DataValueField(nameof(ReferenceCodeDTO.ID))
                                            .DataTextField(nameof(ReferenceCodeDTO.Label))
.Filter(FilterType.Contains)
                                            .HtmlAttributes(new { style = "width: 100%", tabindex = ++tabIndex })
                                            .ValuePrimitive(true)
                                            .OptionLabel("")
                                            .HtmlAttributes(new { style= "aria-labelledby:OfficerIDTypeID" })
                                            .BindTo(await refCodeLookupHelper.GetCodesByReferenceCodeType("PersonIdentifierTypeKey"))
                                            .Events(e => e.Change("onChangeOfficerTypeId"))
                                            )

Hi Kris,

Thank you for the great addition. Indeed, when the label is not visible, the aria-label attribute has to be added as well.

Hi Tsvetomir,

Thank you replying with the suggestion

I have to do this in order make the WAVE error go.

 

Thank you

Kris R

function onDataBound(e){
              $("input[role='listbox']").attr("aria-label", "ddl_searchbox");

            }

Hi Kris,

Thank you for sharing the issue that you have encountered. Indeed, this is a miss on our side and I have converted the ticket to an official bug item on our feedback portal.

Until an official fix is available, I can recommend using either of the following options:

1. Set the FilterTitle option, this would resolve the issue, however, it would transform it into a warning.

.FilterTitle("Search")

2. Add a label element and resolve the issue completely.

.Events(ev=>ev.DataBound("onDataBound"))

function onDataBound(e){
              $("input[role='searchbox']").attr("id", "ddl_searchbox");
              $('<label for="ddl_searchbox">Search</label>').insertAfter($("input[role='searchbox']")).hide();
            }

I hope you find this helpful.

 

Kind regards,
Tsvetomir
