❔ Blazor: How to have a component inside a component?

I was reading the mudBlazor documentation and I saw that they call a blazor element and inside that element, they call other elements. I didnt know it was even possible and I have no idea how i can do something like that. I would like to call a component and inside that one, call as much component (that is made to work inside the parent one obviously) as I want. As an exemple, I would like to make a table but the number of columns in unknown before run time. Inside the table component, I would like to be able to call multiple element such as textbox or a combobox. Anyway, something like in the picture.

you create components and nest them? I'm not sure what your question is oh you want something like this?

<ComponentA>
<ComponentB>
</ComponentA>

<ComponentA>
<ComponentB>
</ComponentA>

This would be componentA.razor

<div>This is component A</div>
@Body

@code {
    [Parameter] public RenderFragment Body { get; set; }
}

<div>This is component A</div>
@Body

@code {
    [Parameter] public RenderFragment Body { get; set; }
}

this would be componentB.razor

<div>This is component B</div>

<div>This is component B</div>

I forgot to send the error, my mistake. I will try that asap, thanks!!

would you be able to use the RowTemplate https://mudblazor.com/components/table#table-with-related-data which is already built in

Yeah! I see that blazor librairies have a lot to offer, but i'm trying to understand what is going on behind the scene before starting a project in blazor!
