Selective components do not open (MudSelect, MudMenu, MudDatePicker, etc.) about mudblazor HOT 6 CLOSED

<CascadingValue Value=false Name="UsePopoverProvider"> -- this is your problem.

Why are you setting UsePopoverProvider to false? You should only need that if you are already registering a PopoverProvider somewhere else in your code. It's usually registered within the MudThemeProvider, but your telling the MudThemeProvider to not register it.

Also, if that's all your class does, there is no real need to make your own class, you just need to define your custom MudTheme and do <MudThemeProvider Theme="MyTheme" IsDarkMode="true"/>

@Anu6is This was probably a copy paste error on my part. I have removed this and now it works without any problems. Many thanks for your support.

You are most likely missing something in your setup. Since you've stated that you added the render modes globally, the next possible issues is missing the mud providers in your main layout.

@Anu6is Yes, I have declared the two lines <MudThemeProvider/> and <MudDialogProvider/> in the MainLayout.razor.

Can you share a repo link reproducing the issue?

from mudblazor.

@Anu6is I have tried to create a separate project and reproduce the problem. However, the component works there without any problems. Unfortunately, I cannot publish my code.

I have now found out that the source of the problem is with my costum ThemeProvider. It is structured like this:

<CascadingValue Value=false Name="UsePopoverProvider">
<MudThemeProvider Theme="MyTheme" IsDarkMode="true"></MudThemeProvider>
</CascadingValue>

@code {
public static MudTheme MyTheme => new()
{
PaletteDark = new PaletteDark()
{
Primary = "#e30613",
AppbarBackground = "#1a1e21",
Background = "#1a1e21",
TextPrimary = "#e2e2e2",
Secondary = "#039136",
Black = "#151521",
Dark = "#151521",
Tertiary = "#95a5a6",
},
Typography = new Typography()
{
Default = new Default()
{
FontFamily = new[] { "Roboto", "Verdana", "Geneva"}
},
Button = new Button()
{
TextTransform = "None",
FontSize = "0.85rem"
}
}
};
}

I have the following references in the MainLayout:

<MyMudThemeProvider /> (is like the name of the class)
<MudDialogProvider />
<MudSnackbarProvider />

If I reference the standard <MudThemeProvider/>, the components work.
Do you have any idea what is wrong here?
