`<paper-input-container>` is a container for a `<label>`, an `<input is="iron-input">` or
|
|
`<iron-autogrow-textarea>` and optional add-on elements such as an error message or character
|
|
counter, used to implement Material Design text fields.
|
|
|
|
For example:
|
|
|
|
<paper-input-container>
|
|
<label>Your name</label>
|
|
<input is="iron-input">
|
|
</paper-input-container>
|
|
|
|
Do not wrap `<paper-input-container>` around elements that already include it, such as `<paper-input>`.
|
|
Doing so may cause events to bounce infintely between the container and its contained element.
|
|
|
|
### Listening for input changes
|
|
|
|
By default, it listens for changes on the `bind-value` attribute on its children nodes and perform
|
|
tasks such as auto-validating and label styling when the `bind-value` changes. You can configure
|
|
the attribute it listens to with the `attr-for-value` attribute.
|
|
|
|
### Using a custom input element
|
|
|
|
You can use a custom input element in a `<paper-input-container>`, for example to implement a
|
|
compound input field like a social security number input. The custom input element should have the
|
|
`paper-input-input` class, have a `notify:true` value property and optionally implements
|
|
`Polymer.IronValidatableBehavior` if it is validatable.
|
|
|
|
<paper-input-container attr-for-value="ssn-value">
|
|
<label>Social security number</label>
|
|
<ssn-input class="paper-input-input"></ssn-input>
|
|
</paper-input-container>
|
|
|
|
|
|
If you're using a `<paper-input-container>` imperatively, it's important to make sure
|
|
that you attach its children (the `iron-input` and the optional `label`) before you
|
|
attach the `<paper-input-container>` itself, so that it can be set up correctly.
|
|
|
|
### Validation
|
|
|
|
If the `auto-validate` attribute is set, the input container will validate the input and update
|
|
the container styling when the input value changes.
|
|
|
|
### Add-ons
|
|
|
|
Add-ons are child elements of a `<paper-input-container>` with the `add-on` attribute and
|
|
implements the `Polymer.PaperInputAddonBehavior` behavior. They are notified when the input value
|
|
or validity changes, and may implement functionality such as error messages or character counters.
|
|
They appear at the bottom of the input.
|
|
|
|
### Prefixes and suffixes
|
|
These are child elements of a `<paper-input-container>` with the `prefix`
|
|
or `suffix` attribute, and are displayed inline with the input, before or after.
|
|
|
|
<paper-input-container>
|
|
<div prefix>$</div>
|
|
<label>Total</label>
|
|
<input is="iron-input">
|
|
<paper-icon-button suffix icon="clear"></paper-icon-button>
|
|
</paper-input-container>
|
|
|
|
### Styling
|
|
|
|
The following custom properties and mixins are available for styling:
|
|
|
|
Custom property | Description | Default
|
|
----------------|-------------|----------
|
|
`--paper-input-container-color` | Label and underline color when the input is not focused | `--secondary-text-color`
|
|
`--paper-input-container-focus-color` | Label and underline color when the input is focused | `--primary-color`
|
|
`--paper-input-container-invalid-color` | Label and underline color when the input is is invalid | `--error-color`
|
|
`--paper-input-container-input-color` | Input foreground color | `--primary-text-color`
|
|
`--paper-input-container` | Mixin applied to the container | `{}`
|
|
`--paper-input-container-disabled` | Mixin applied to the container when it's disabled | `{}`
|
|
`--paper-input-container-label` | Mixin applied to the label | `{}`
|
|
`--paper-input-container-label-focus` | Mixin applied to the label when the input is focused | `{}`
|
|
`--paper-input-container-label-floating` | Mixin applied to the label when floating | `{}`
|
|
`--paper-input-container-input` | Mixin applied to the input | `{}`
|
|
`--paper-input-container-underline` | Mixin applied to the underline | `{}`
|
|
`--paper-input-container-underline-focus` | Mixin applied to the underline when the input is focused | `{}`
|
|
`--paper-input-container-underline-disabled` | Mixin applied to the underline when the input is disabled | `{}`
|
|
`--paper-input-prefix` | Mixin applied to the input prefix | `{}`
|
|
`--paper-input-suffix` | Mixin applied to the input suffix | `{}`
|
|
|
|
This element is `display:block` by default, but you can set the `inline` attribute to make it
|
|
`display:inline-block`.
