DropDown grouping with multiple select - minor issues and feedback

Hello Radzen Team

Really enjoy the new features for grouping a RadzenDropDown with multiple selection. Just want to give some feedback for problems i have encountered when using it.

I have used this #multiple-selection example from your site and adjusted it to my needs.

  • The AllowClear="true" does clear the selected items, however when opening the dropdown, all the items are still checked in the checkboxes (this occurs in your example also).

  • I have been unable to make the dropdown work with any of your Validators when its inside a submit form. I have tried both with a <RadzenFormField> and just plain example without.

  • When the dropdown is open, i have to click the actual checkbox for it to check/uncheck. I am unable to click the corrosponding text to do it (like in the normal multiple select dropdown example).

  • Using the TextProperty="" on the DropDown does also seem to behave in a wired way. It seems it tries to find the property of Data=@groupedData collection instead of the Value=@values TValue="IEnumerable<int>" collection (when using complex objects instead of primitive types).

Thanks in advance and have a nice day.

I've just pushed some improvements, mainly using @bind-Value to enable AllowClear and Form/Validators to work properly and toggling the CheckBox by clicking the label. Feel free to adapt the binding, selection and the entire example itself to your case in the way you need.
