MudBlazor - Blazor Component Library

Note: When using this component it can be good to have some CSS knowledge it might not serve all types of content out of the box.

<MudButton Variant="Variant.Filled" Color="Color.Primary" OnClick="@ToggleOpen">Open</MudButton>
<MudSwitch @bind-Value="_open" Color="Color.Primary" />
<MudToggleIconButton @bind-Toggled="@_open" Icon="@Icons.Material.Filled.Fullscreen" Color="@Color.Primary" ToggledIcon="@Icons.Material.Filled.FullscreenExit" ToggledColor="@Color.Secondary" />

<MudPopover Open="@_open" Fixed="true" Class="px-4 pt-4">
    <div class="d-flex flex-column">
        <MudText>Content of the popover can be anything.</MudText>
        <MudButton OnClick="@ToggleOpen" Class="ml-auto mr-n3 mb-1" Color="Color.Error">Close</MudButton>
    </div>
</MudPopover>

@code{
    private bool _open;

    private void ToggleOpen() => _open = !_open;
}

Direction and Location

Note: the location can be set with custom css or using the style tag.

Control where the popover should start from relative to the parent. Offset the popover to be located outside of the parent.

Overflow Behavior

You can set the overflow behavior of the popover to either FlipNever, FilpOnOpen or FlipAlways
Resize your browser window slowly so the popover wont fit to see result in flip mode.

<MudPaper Outlined="true" Class="px-12 py-6">
    <MudButton Variant="Variant.Filled" Color="Color.Primary" DropShadow="false" OnClick="@ToggleOpen">@(_open? "Close" : "Open")</MudButton>
    <MudPopover Open="_open" OverflowBehavior="OverflowBehavior.FlipAlways" AnchorOrigin="Origin.BottomCenter" TransformOrigin="Origin.TopCenter" Paper="false">
        <MudPaper Outlined="true" Class="px-4 py-8">
            <MudText>Scroll your browser to see effect.</MudText>
        </MudPaper>
    </MudPopover>
</MudPaper>

@code {
    private bool _open = true;

    private void ToggleOpen() => _open = !_open;
}

Complex Content

You can have any content within a popover like with any other Blazor component. The position of the popover is updated automatically

<div class="d-flex">
    <MudButton Variant="Variant.Filled" Color="Color.Primary" OnClick="@ToggleOpen">
        @(_open? "Close" : "Open")
    </MudButton>
    <MudPopover Open="@_open" AnchorOrigin="Origin.BottomCenter" TransformOrigin="Origin.TopCenter">
        <div class="d-flex flex-column pa-1">
            <PopoverDynamicContentExample />
        </div>
    </MudPopover>
</div>

@code {

    public bool _open;

    public void ToggleOpen()
    {
        if (_open)
            _open = false;
        else
            _open = true;
    }
}

<MudMenu Class="" Label="A menu with tooltip" Variant="Variant.Filled" Color="Color.Primary">
    <div class="d-flex align-center">
        <MudText Class="ml-4">1</MudText>
        <MudTooltip Text="1 is good option">
            <MudIconButton Class="mx-2" Icon="@Icons.Material.Outlined.Info" />
        </MudTooltip>
    </div>
    <div class="d-flex align-center">
        <MudText Class="ml-4">2</MudText>
        <MudMenu Icon="@Icons.Material.Outlined.Mouse" ActivationEvent="@MouseEvent.MouseOver" Class="mx-2">
            <ChildContent>
                <MudMenuItem>Profile</MudMenuItem>
                <MudMenuItem>Theme</MudMenuItem>
                <MudMenuItem>Usage</MudMenuItem>
                <MudMenuItem>Sign Out</MudMenuItem>
            </ChildContent>
        </MudMenu>
        <MudTooltip Text="2 can be a better option">
            <MudIconButton Class="mx-2" Icon="@Icons.Material.Outlined.Info" />
        </MudTooltip>
    </div>
    <div class="d-flex align-center">
        <MudText Class="ml-4">3</MudText>
        <MudTooltip Text="3 is one more than 2">
