Is there any way to disable an item from a dropdown whose list of items is fixed?

Radzen.Blazor Components
1 
private Dictionary<string, string> genderList = new Dictionary<string, string>()
{
    {"MALE","Male"},
    {"FEMALE","female"},
};

<RadzenDropDown Name="SelectGender"
                AllowClear="true"
                AllowFiltering="true"
                FilterCaseSensitivity="FilterCaseSensitivity.CaseInsensitive"
                Data="genderList"
                @bind-Value="model.TP_GENDER"
                Placeholder="Select an option..."
                TextProperty="Value"
                ValueProperty="Key"
                DisabledProperty="MALE"
                TValue="string"
                class="w-100" />

I tried passing the name of the property that I want to disable as it says in the documentation, using the DisabledProperty="MALE" option but it didn't work.

It generated an error saying that this property does not exist in the list.

You will need to convert your dictionary to enumerable of objects with properties.
