I made a Blazor REPL reproduction: https://blazorrepl.telerik.com/mcuCGpYr4223mhWY49. Run and observe the person label is overlapping the dropdown.

How to reproduce:

1. Get code from the Remote Data Example.
2. Surround the ComboBox with a TelerikFloatingLabel, it will then look like this:

   <TelerikFloatingLabel Text="Person">
   <TelerikComboBox 
                   TItem="@Person" TValue="@int"
                    ScrollMode="@DropDownScrollMode.Virtual"
                    OnRead="@GetRemoteData"
                    ValueMapper="@GetModelFromValue"
                    ItemHeight="30"
                    PageSize="20"
                    TextField="@nameof(Person.Name)"
                    ValueField="@nameof(Person.Id)"
                    @bind-Value="@SelectedValue"
                    Filterable="true" FilterOperator="@StringFilterOperator.Contains">
       <ComboBoxSettings>
           <ComboBoxPopupSettings Height="200px" />
       </ComboBoxSettings>    
   </TelerikComboBox>
   </TelerikFloatingLabel>

The FloatingLabel does not have a Size setting. Thus, if I use it together with a large TextBox, there is a discrepancy between the font-sizes of the FloatingLabel and the TextBox value.

Please allow setting the size of the component.

ADMIN EDIT

A possible solution for the time being is to use CSS to adjust the font-size of the FloatingLabel, so it matches the TextBox.

I have a flag for Enabling/Disabling a ComboBox. It works without the floating label. With the floating label, I cannot get the ComboBox to recognize the flag changing.

The first box will not re-enable with the button click, but the second enables/disables as many times as you click the button. Here is the code:

<h3>TestPage</h3>

<TelerikButton OnClick="@(() => {_isEnabled = !_isEnabled;})">Is Enabled: @_isEnabled.ToString() </TelerikButton>

<TelerikFloatingLabel Class="otis-fl-100"
                      Text="Select a Form">
    <TelerikComboBox Data="@_data"
                     Width="100%"
                     TValue="string"
                     TItem="string"
                     Filterable="true"
                     Enabled="@_isEnabled">
    </TelerikComboBox>
</TelerikFloatingLabel>

<br />
<br />

<TelerikComboBox Data="@_data"
                 Width="100%"
                 TValue="string"
                 TItem="string"
                 Filterable="true"
                 Placeholder="Select a Form"
                 Enabled="@_isEnabled">
</TelerikComboBox>

@code {
    private List<string> _data = new List<string> { "one", "two", "three" };
    private bool _isEnabled = true;
}
