13 `<paper-input-container>` is a container for a `<label>`, an `<input is="iron-in
put">` or | |
14 `<iron-autogrow-textarea>` and optional add-on elements such as an error message
or character | |
15 counter, used to implement Material Design text fields. | |
16 | |
17 For example: | |
18 | |
19 <paper-input-container> | |
20 <label>Your name</label> | |
21 <input is="iron-input"> | |
22 </paper-input-container> | |
23 | |
24 ### Listening for input changes | |
25 | |
26 By default, it listens for changes on the `bind-value` attribute on its children
nodes and perform | |
27 tasks such as auto-validating and label styling when the `bind-value` changes. Y
ou can configure | |
28 the attribute it listens to with the `attr-for-value` attribute. | |
29 | |
30 ### Using a custom input element | |
31 | |
32 You can use a custom input element in a `<paper-input-container>`, for example t
o implement a | |
33 compound input field like a social security number input. The custom input eleme
nt should have the | |
34 `paper-input-input` class, have a `notify:true` value property and optionally im
plements | |
35 `Polymer.IronValidatableBehavior` if it is validatble. | |
36 | |
37 <paper-input-container attr-for-value="ssn-value"> | |
38 <label>Social security number</label> | |
39 <ssn-input class="paper-input-input"></ssn-input> | |
40 </paper-input-container> | |
41 | |
42 ### Validation | |
43 | |
44 If the `auto-validate` attribute is set, the input container will validate the i
nput and update | |
45 the container styling when the input value changes. | |
46 | |
47 ### Add-ons | |
48 | |
49 Add-ons are child elements of a `<paper-input-container>` with the `add-on` attr
ibute and | |
50 implements the `Polymer.PaperInputAddonBehavior` behavior. They are notified whe
n the input value | |
51 or validity changes, and may implement functionality such as error messages or c
haracter counters. | |
52 They appear at the bottom of the input. | |
53 | |
54 ### Styling | |
55 | |
56 The following custom properties and mixins are available for styling: | |
57 | |
58 Custom property | Description | Default | |
59 ----------------|-------------|---------- | |
60 `--paper-input-container-color` | Label and underline color when the input is no
t focused | `--secondary-text-color` | |
61 `--paper-input-container-focus-color` | Label and underline color when the input
is focused | `--default-primary-color` | |
62 `--paper-input-container-invalid-color` | Label and underline color when the inp
ut is focused | `--google-red-500` | |
63 `--paper-input-container-input-color` | Input foreground color | `--primary-text
-color` | |
64 `--paper-input-container` | Mixin applied to the container | `{}` | |
65 `--paper-input-container-label` | Mixin applied to the label | `{}` | |
66 `--paper-input-container-input` | Mixin applied to the input | `{}` | |
67 | |
68 This element is `display:block` by default, but you can set the `inline` attribu
te to make it | |
69 `display:inline-block`. | |
