A small, non-disruptive popup for messages.
<h3>Overview</h3>
A message toast is a small, non-disruptive popup for success or information messages that disappears automatically after a few seconds.
Toasts automatically disappear after a timeout unless the user moves the mouse over the toast or taps on it.
<h4>Notes:</h4>
<ul>
<li>If the configured message contains HTML code or script tags, those will be escaped.</li>
<li>Line breaks (\r\n, \n\r, \r, \n) will be visualized.</li>
<li>Only one message toast can be shown at a time in the same place.</li>
</ul>
<h4>Example:</h4>
Here is an example of a MessageToast with all default options:
<pre>
sap.m.MessageToast.show("This message should appear in the message toast", {
    duration: 3000,                  // default
    width: "15em",                   // default
    my: "CenterBottom",             // default
    at: "CenterBottom",             // default
    of: window,                      // default
    offset: "0 0",                   // default
    collision: "fit fit",            // default
    onClose: null,                   // default
    autoClose: true,                 // default
    animationTimingFunction: "ease", // default
    animationDuration: 1000,         // default
    closeOnBrowserNavigation: true   // default
});
</pre>
<h3>Usage</h3>
<h4>When to use:</h4>
<ul>
<li>You want to display a short success of information message.</li>
<li>You do not want to interrupt users while they are performing an action.</li>
<li>You want to confirm a successful action.</li>
</ul>
<h4>When not to use:</h4>
<ul>
<li>You want to display an error or warning message.</li>
<li>You want to interrupt users while they are performing an action.</li>
<li>You want to make sure that users read the message before they leave the page.</li>
<li>You want users to be able to copy some part of the message text. (In this case, show a success {@link sap.m.Dialog Message Dialog}.)</li>
</ul>
<h3>Responsive Behavior</h3>
The message toast has the same behavior on all devices. However, you can adjust the width of the control, for example, for use on a desktop device.
