## Solution
To implement a responsible popup that can be minimized to the bottom of the page:

1. Set the `Top` and `Left` parameters to control the position of the modal.
2. Use boolean flags to show and hide the popup.
3. Use the [MediaQuery](slug://mediaquery-overview) component to make the modal window responsive.

### Minimize Window to the Bottom Right

![Blazor Window Small Screen](images/window-small-screen.gif)
To minimize the Window to the bottom-right corner of the viewport:

````Razor
@*Responsive minimizable popup.*@
1. Set a custom CSS class to the Window with the `Class` parameter, for example, `minimized-at-bottom`.
1. Apply the following styles to the `.k-window-minimized.minimized-at-bottom` CSS combinator:
* `top` and `left` must be `auto !important`
* `bottom` and `right` must be zero or an arbitrary small value
* `transform` must be `none`

<TelerikMediaQuery Media="(max-width: 960px)" OnChange="((changed) => Small = changed)"></TelerikMediaQuery>
````RAZOR
<TelerikButton OnClick="@( () => WindowVisible = !WindowVisible )">Toggle Window</TelerikButton>
<TelerikWindow Class="@myClass" Modal="@isModal"
Top="@TopPosition"
Left="@LeftPosition"
@bind-Visible="@isModalVisible">
<TelerikWindow @bind-Visible="@WindowVisible"
Class="minimized-at-bottom">
<WindowActions>
<WindowAction Name="Minimize" />
<WindowAction Name="Close" />
</WindowActions>
<WindowTitle>
<strong>@Title</strong>
Window Title
</WindowTitle>
<WindowContent>
@if (isModal)
{
@Content
}
Window Content
</WindowContent>
</TelerikWindow>
<style>
.k-window-minimized.minimized-at-bottom {
top: auto !important;
left: auto !important;
bottom: 1em;
right: 1em;
transform: none;
}
</style>
@code {
private bool WindowVisible { get; set; } = true;
}
````

### Create Responsive Chat Window

To configure a responsive popup Window that transforms to a chat bubble on small screens:

1. Use the [MediaQuery component](slug://mediaquery-overview) to make the Window responsive and change its configuration, depending on the browser viewport size.
1. Use custom CSS classes and styles to tweak the Window appearance and make it look like a bubble when minimized.

````RAZOR
<TelerikMediaQuery Media="(max-width: 960px)"
OnChange="@( (bool matches) => IsSmallScreen = matches )" />
<TelerikWindow Class="@WindowClass"
MinWidth="140px"
@bind-State="@WindowState"
ThemeColor="@ThemeConstants.Window.ThemeColor.Primary"
Visible="true">
<WindowTitle>@WindowTitle</WindowTitle>
<WindowContent>
<p>The Window title changes, depending on the browser viewport size.</p>
<p>Reduce the browser width and minimize the Window to minimize it as a chart bubble at the bottom-right.</p>
</WindowContent>
<WindowActions>
<WindowAction Name="MyMinimizer" Hidden="@(!isModal)" Icon="@SvgIcon.WindowMinimize" OnClick="@MyCustomMinimize" />
<WindowAction Name="MyExpander" Hidden="@isModal" Icon="@SvgIcon.Window" OnClick="@MyCustomExpand" />
<WindowAction Name="Minimize" />
</WindowActions>
</TelerikWindow>
