| 11 `paper-toast` provides lightweight feedback about an operation in a small popup | |
| 12 at the base of the screen on mobile and at the lower left on desktop. Toasts are
| |
| 13 above all other elements on screen, including the FAB. | |
| 14 | |
| 15 Toasts automatically disappear after a timeout or after user interaction | |
| 16 elsewhere on the screen, whichever comes first. Toasts can be swiped off | |
| 17 screen. There can be only one on the screen at a time. | |
| 18 | |
| 19 Example: | |
| 20 | |
| 21 <paper-toast text="Your draft has been discarded." onclick="discardDraft(el)
"></paper-toast> | |
| 22 | |
| 23 <script> | |
| 24 function discardDraft(el) { | |
| 25 el.show(); | |
| 26 } | |
| 27 </script> | |
| 28 | |
| 29 An action button can be presented in the toast. | |
| 30 | |
| 31 Example (using Polymer's data-binding features): | |
| 32 | |
| 33 <paper-toast id="toast2" text="Connection timed out. Showing limited message
s."> | |
| 34 <div style="color: blue;" on-tap="{{retry}}">Retry</div> | |
| 35 </paper-toast> | |
| 36 | |
| 37 Positioning toast: | |
| 38 | |
| 39 A standard toast appears near the lower left of the screen. You can change the | |
| 40 position by overriding bottom and left positions. | |
| 41 | |
| 42 paper-toast { | |
| 43 bottom: 40px; | |
| 44 left: 10px; | |
| 45 } | |
| 46 | |
| 47 To position the toast to the right: | |
| 48 | |
| 49 paper-toast { | |
| 50 right: 10px; | |
| 51 left: auto; | |
| 52 } | |
| 53 | |
| 54 To make it fit at the bottom of the screen: | |
| 55 | |
| 56 paper-toast { | |
| 57 bottom: 0; | |
| 58 left: 0; | |
| 59 width: 100%; | |
| 60 } | |
| 61 | |
| 62 When the screen size is smaller than the `responsiveWidth` (default to 480px), | |
| 63 the toast will automatically fits at the bottom of the screen. | |
