Hi Team, 

I would like to request a configuration for the Kendo UI Form to place the validation message in other positions such as above or below the editor. 

Thanks!

Please add support for nesting groups in the form-control. 

As written on your page https://docs.telerik.com/kendo-ui/controls/form/groups nesting of groups is not supported.  

As we are developing a highly configurable software we have the need to edit properties of json-objects via UI for the needs of our customers. A schema for validating fields and so on exists, but unfortunately we cannot use "form"-Control because the objects do have nested objects in multiple hierachy levels. 

Therefore nesting of groups would be really great.

Bug report
Custom Validation Message for RadioGroup/CheckBoxGroup in a Form is not reflected

Bug report

A Form group label encoded option cannot be set to false.

Reproduction of the problem

1. Open this Dojo example - https://dojo.telerik.com/eGEqEbEw/8

Current behavior

The HTML is not decoded

Expected/desired behavior

The HTML in the text configuration should be decoded

Environment

• Kendo UI version: 2022.2.621
• Browser: [all]

Currently, a Form should be initialized from a <form> tag. When the Form is created from <div> tag it is not submitted and the submit event is not fired. I would like to have the possibility to initialize and submit a Form initialised from <div>.

Hi Team,

I would like to request that when the Kendo UI Form submits a checkbox boolean value to pass as True/False instead of On/Off. Currently, I am using a custom editor which will perform the true/false submission.

Thank you!

Hi Team,

I would like to request adding a simple checkbox into the items.editor instead of just the switch.  This would be great if the k-checkbox-label was also included with the editor.

Currently I have a solution in which I can create a checkbox editor, but it could be so much better if I didn't have to write an extra editor function for a simple checkbox.

Thank you for your consideration

Please provide support for the Upload as built-in editor in the Form.

Currently Kendo UI for jQuery Form group appearance may be customized by custom CSS. The following Dojo snippet shows group customization to resemble Bootstrap 4 cards. But it would be helpful to provide a property named for example groupAttributes, which sets CSS classes and other HTML attributes to style the generated group sections. This would allow setting Bootstrap 4's card classes.

Add support for the ButtonGroup as Custom Editor and update the ImageEditor to use it. This way the Orientation in the Crop pane can be programmatically set using the model set method.

Currently, the Form displays the validation messages below the respective fields that failed the validation. It would be nice, if there is an option to show them in a tooltip.

Hi,

Is there any example for a jquery button changing the component inside the form?

For example

1. press a button > add a new input row in the form

2. press a button > change the component in one row in form

 

Thanks.

 

It will be good to have a method in the Form API to get or set the Form model. For example, it could be:

var form = $("#form").getKendoForm();
var model = form.model();

When a form creates a group it uses a fieldset.  It would be great if this fieldset could have an id or class so it can be manipulated easily.

Whilst I could write code to find the Nth fieldset and modify it, it would be much cleaner to allow an id to be set on it.
