How to remove unused blank line?

Go here: https://demos.telerik.com/kendo-ui/multiselect/index

and select Anne King, Andrew Fuller and Nancy Leverling.

MultiSelect now uses two lines and the second line is blank, even after the widget loses focus.

How can I get rid of this extra blank line?

My page has lots of stuff on it, and the extra line causes most of the page to shift down.

Search not working with React material-table using remote data

I'm using the material-table module here [1] with remote data from a web service. I've included the search parameter, but it's not working and there are no error messages in the console.

Here is the code:

import React from 'react';
import ReactDOM from "react-dom";
import MaterialTable from 'material-table';


import { forwardRef } from 'react';

import AddBox from '@material-ui/icons/AddBox';
import ArrowUpward from '@material-ui/icons/ArrowUpward';
import Check from '@material-ui/icons/Check';
import ChevronLeft from '@material-ui/icons/ChevronLeft';
import ChevronRight from '@material-ui/icons/ChevronRight';
import Clear from '@material-ui/icons/Clear';
import DeleteOutline from '@material-ui/icons/DeleteOutline';
import Edit from '@material-ui/icons/Edit';
import FilterList from '@material-ui/icons/FilterList';
import FirstPage from '@material-ui/icons/FirstPage';
import LastPage from '@material-ui/icons/LastPage';
import Remove from '@material-ui/icons/Remove';
import SaveAlt from '@material-ui/icons/SaveAlt';
import Search from '@material-ui/icons/Search';
import ViewColumn from '@material-ui/icons/ViewColumn';

const tableIcons = {
    Add: forwardRef((props, ref) => <AddBox {...props} ref={ref} />),
    Check: forwardRef((props, ref) => <Check {...props} ref={ref} />),
    Clear: forwardRef((props, ref) => <Clear {...props} ref={ref} />),
    Delete: forwardRef((props, ref) => <DeleteOutline {...props} ref={ref} />),
    DetailPanel: forwardRef((props, ref) => <ChevronRight {...props} ref={ref} />),
    Edit: forwardRef((props, ref) => <Edit {...props} ref={ref} />),
    Export: forwardRef((props, ref) => <SaveAlt {...props} ref={ref} />),
    Filter: forwardRef((props, ref) => <FilterList {...props} ref={ref} />),
    FirstPage: forwardRef((props, ref) => <FirstPage {...props} ref={ref} />),
    LastPage: forwardRef((props, ref) => <LastPage {...props} ref={ref} />),
    NextPage: forwardRef((props, ref) => <ChevronRight {...props} ref={ref} />),
    PreviousPage: forwardRef((props, ref) => <ChevronLeft {...props} ref={ref} />),

Move scrollbar of long table with locked columns below footer but keep footer in view

Dojo

The above Dojo shows my code. I have a table with many rows. I want the first row locked and the table has a footer. I want the footer to remain visible regardless or where the user scrolls vertically. I want the footer to track horizontally with the rest of the table though so the columns stay lined up. This has to also be responsive so it works on various screen sizes and devices. I tried the sample in one of the previous questions on here but that doesn't work with the conditions mentioned above. How would I accomplish this?

How to validate an optional date with a date input mask

I have a dateinput field that I need to validate. Unfortunately I can't seem to figure out how to make it work. The requirements are as follows:

1. The date is optional.

2. If the date is provided, it must be a valid date.

3. The input mask could be in various languages.

When I try to validate I get invalid date when the date field just has the input mask (month/day/year) showing.

Here is a dojo showing my example.

One validation error for group of checkboxes

I have a list of checkboxes and I need to validate if at least one is checked. If not, I want one error message to appear for the entire group. That message should appear in a separate <span></span> below the group. I know how to do this with radio buttons but these are checkboxes so they can't all have the same name. I've looked at the other posts on here from 2013, 2015, and 2019 but none of them really answer my question. How would I do something like that?

autocomplete attribute on AutoComplete widget

How can I set the HTML autocomplete attribute on an input which uses Kendo UI AutoComplete widget to a value other than "off"?

So far, I have tried the following code:

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <title>Untitled</title>

  <link rel="stylesheet" href="https://kendo.cdn.telerik.com/2021.3.1109/styles/kendo.common.min.css">
  <link rel="stylesheet" href="https://kendo.cdn.telerik.com/2021.3.1109/styles/kendo.rtl.min.css">
  <link rel="stylesheet" href="https://kendo.cdn.telerik.com/2021.3.1109/styles/kendo.default.min.css">
  <link rel="stylesheet" href="https://kendo.cdn.telerik.com/2021.3.1109/styles/kendo.mobile.all.min.css">

  <script src="https://code.jquery.com/jquery-1.12.3.min.js"></script>
  <script src="https://kendo.cdn.telerik.com/2021.3.1109/js/angular.min.js"></script>
  <script src="https://kendo.cdn.telerik.com/2021.3.1109/js/jszip.min.js"></script>
  <script src="https://kendo.cdn.telerik.com/2021.3.1109/js/kendo.all.min.js"></script></head>
<body>
  <input type="text" id="countries" autocomplete="one-time-code" />
  <script>
  $(function(){
      
      var countries = [ "Australia", "Canada", "United States of America"];
    
      var countriesDataSource = new kendo.data.DataSource({
        data: countries
      });
      $('#countries').kendoAutoComplete({
        dataSource: countriesDataSource
      });
  });
  </script>
</body>
</html>

But if you see the screenshot, no matter the HTML markup, the input gets the autocomplete="off" attribute (and value). Guessing this is part of the autocomplete widget?

I am trying to get round the Chrome issue reported here where the previous input to an input[type=password] is autofilled with a username / email.

So want to know how to set the autocomplete attribute on a Kendo-ified AutoComplete input, to a value of my choice.

Alternatively, any solid method of avoiding Chrome autofill on the Kendo UI AutoComplete widget would be greatly appreciated.

Thanks in advance

What's causing the row height styles being added to every row in virtual scroll and how do I stop it?

When scrolling with frozen columns and virtual scrolling enabled, the grid freezes a few seconds when you scroll back up to previously loaded rows. Looks like kendo is adding inline height styles to each row that's causing the jank.

I see in the demos for frozen columns and virtual scrolling this does not happen. Is this being cause by a specific grid setting that we have? Is it possible to disable this?

MaskedTextBox mask doesn't work correctly with promptChar: "" or " "

Hello,

I tried to hide the mask prompt characters. But I got strange results.

If I use empty string as a promptChar

input.kendoMaskedTextBox({ mask: "&", promptChar: "" });

then the mask doesn't work at all.

When I use a space as a promptChar

input.kendoMaskedTextBox({ mask: "&", promptChar: " " });

then the mask enforces the length but not contents - I can enter a space even when I shouldn't be able.

When I use an underscore as a promptChar or use default

input.kendoMaskedTextBox({ mask: "&", promptChar: "_" });
input.kendoMaskedTextBox({ mask: "&" });

then everything works as it should, I can enter only one character but not a space.

Is this a feature or a bug? I'm using Kendo UI v2021.1.119.
