     20 ##&lt;iron-autogrow-textarea&gt;
     21 
     22 `iron-autogrow-textarea` is an element containing a textarea that grows in height as more
     23 lines of input are entered. Unless an explicit height or the `maxRows` property is set, it will
     24 never scroll.
     25 
     26 Example:
     27 
     28 ```html
     29 <iron-autogrow-textarea></iron-autogrow-textarea>
     30 ```
     31 
     32 Because the `textarea`'s `value` property is not observable, you should use
     33 this element's `bind-value` instead for imperative updates.
