12 `iron-collapse` creates a collapsible block of content. By default, the content | |
13 will be collapsed. Use `opened` or `toggle()` to show/hide the content. | |
14 | |
15 <button on-click="{{toggle}}">toggle collapse</button> | |
16 | |
17 <iron-collapse id="collapse"> | |
18 <div>Content goes here...</div> | |
19 </iron-collapse> | |
20 | |
21 ... | |
22 | |
23 toggle: function() { | |
24 this.$.collapse.toggle(); | |
25 } | |
26 | |
27 `iron-collapse` adjusts the height/width of the collapsible element to show/hide | |
28 the content. So avoid putting padding/margin/border on the collapsible directly
, | |
29 and instead put a div inside and style that. | |
30 | |
31 <style> | |
32 .collapse-content { | |
33 padding: 15px; | |
34 border: 1px solid #dedede; | |
35 } | |
36 </style> | |
37 | |
38 <iron-collapse> | |
39 <div class="collapse-content"> | |
40 <div>Content goes here...</div> | |
41 </div> | |
42 </iron-collapse> | |
