The dropdown (select) components such as ComboBox, MultiSelect etc. have a built-in loading indicator that includes several Skeleton instances.

I want to be able to remove that and add my custom loading indicator in the popup. Ideally, it would be a template so we could have some flexibility.

This request targets all the select components (AutoComplete, ComboBox, DropDownList, MultiColumnComboBox, MultiSelect).

The DropDownList currently does not have a built-in loader but that will be added as well as a prerequisite for the current feature. See Add a loading indicator in the popup.

My question is regarding MultiSelect. I would like to order the groups inside the MultiSelect as follows:

Category 2

- Item 1

- Item 2

Category 1

- Item 3

- Item 4

But the MultiSelect control seems to order the category name alphabetically (Category 1, Category 2, etc).

Hi,

I would like checkbox support including the check all checkbox on the multiselect component like: https://docs.telerik.com/devtools/aspnet-ajax/controls/combobox/functionality/checkbox-support

The url below shows how to create custom checkboxes in the multiselect component but adding a check all checkbox in the headertemplate does not update the multiselect popup

https://docs.telerik.com/blazor-ui/knowledge-base/multiselect-checkbox-in-dropdown?_ga=2.50111909.206897922.1631541466-694624900.1630583797&_gac=1.246637872.1631604077.EAIaIQobChMI8PnX6Pb98gIVkwCLCh381AjMEAAYASAAEgLROPD_BwE

I have a custom ICollection which I wanted to use with the MultiSelect control, however, the Value property is of type List<T>. This is very restrictive; the property should implement an interface for flexibility.
