3 `iron-collapse` creates a collapsible block of content. By default, the content | |
4 will be collapsed. Use `opened` or `toggle()` to show/hide the content. | |
5 | |
6 ```html | |
7 <button on-click="toggle">toggle collapse</button> | |
8 | |
9 <iron-collapse id="collapse"> | |
10 <div>Content goes here...</div> | |
11 </iron-collapse> | |
12 ``` | |
13 | |
14 ```javascript | |
15 toggle: function() { | |
16 this.$.collapse.toggle(); | |
17 } | |
18 ``` | |
19 | |
20 `iron-collapse` adjusts the height/width of the collapsible element to show/hide | |
21 the content. So avoid putting padding/margin/border on the collapsible directly
, | |
22 and instead put a div inside and style that. | |
23 | |
24 ```html | |
25 <style> | |
26 .collapse-content { | |
27 padding: 15px; | |
28 border: 1px solid #dedede; | |
29 } | |
30 </style> | |
31 | |
32 <iron-collapse> | |
33 <div class="collapse-content"> | |
34 <div>Content goes here...</div> | |
35 </div> | |
36 </iron-collapse> | |
37 ``` | |
