Description
sp-textfield[multiline] components are text areas that allow users to input custom multiline text entries with a keyboard. Various decorations can be displayed around the field to communicate the entry requirements.
Usage
yarn add @spectrum-web-components/textfield
Import the side effectful registration of <sp-textfield> via:
import '@spectrum-web-components/textfield/sp-textfield.js';
When looking to leverage the Textfield base class as a type and/or for extension purposes, do so via:
import { Textfield } from '@spectrum-web-components/textfield';
Sizes
<sp-field-label size="s" for="story-0-s">Background</sp-field-label> <sp-textfield size="s" id="story-0-s" multiline placeholder="Enter your life story" ></sp-textfield>
<sp-field-label for="story-0-m">Background</sp-field-label> <sp-textfield id="story-0-m" multiline placeholder="Enter your life story" ></sp-textfield>
<sp-field-label size="l" for="story-0-l">Background</sp-field-label> <sp-textfield size="l" id="story-0-l" multiline placeholder="Enter your life story" ></sp-textfield>
<sp-field-label size="xl" for="story-0-xl">Background</sp-field-label> <sp-textfield size="xl" id="story-0-xl" multiline placeholder="Enter your life story" ></sp-textfield>
Variants
Valid
Dictate the validity state of the text entry with the valid attribute.
<sp-field-label for="story-1" required>Background</sp-field-label> <sp-textfield id="story-1" multiline placeholder="Enter your name" valid ></sp-textfield>
Invalid
Dictate the invalidity state of the text entry with the invalid attribute.
<sp-field-label for="story-2" required>Background</sp-field-label> <sp-textfield id="story-2" invalid multiline placeholder="Enter your name" ></sp-textfield>
Quiet
The quiet style works best when a clear layout (vertical stack, table, grid) assists in a user's ability to parse the element. Too many quiet components in a small space can be hard to read.
<sp-field-label for="story-3">Background (quietly)</sp-field-label> <sp-textfield id="story-3" multiline placeholder="Enter your name" quiet ></sp-textfield>
Grows
By default the text area has a fixed height and will scroll when text entry goes beyond the available space. With the use of the grows attribute the text area will grow to accommodate the full content of the element.
<div style="display: flex; flex-wrap: wrap;"> <div> <sp-field-label for="story-4">Background</sp-field-label> <sp-textfield id="story-4" multiline placeholder="Enter your name" value="By default the text area has a fixed height and will scroll when text entry goes beyond the available space. With the use of the `grows` attribute the text area will grow to accommodate the full content of the element." ></sp-textfield> </div> <div> <sp-field-label for="story-5">Background</sp-field-label> <sp-textfield id="story-5" grows multiline placeholder="Enter your name" value="By default the text area has a fixed height and will scroll when text entry goes beyond the available space. With the use of the `grows` attribute the text area will grow to accommodate the full content of the element." ></sp-textfield> </div> <div> <sp-field-label for="story-6">Background (quietly)</sp-field-label> <sp-textfield id="story-6" grows multiline placeholder="Enter your name" value="By default the text area has a fixed height and will scroll when text entry goes beyond the available space. With the use of the `grows` attribute the text area will grow to accommodate the full content of the element." quiet ></sp-textfield> </div> </div>
Help text
Help text can be accessibly associated with an <sp-textfield multiline> element by using the help-text or negative-help-text slots. When using the negative-help-text slot, <sp-textfield multiline> will self manage the presence of this content based on the value of the invalid property on your <sp-textfield multiline> element. Content within the help-text slot will be show by default. When your <sp-textfield multiline> should receive help text based on state outside of the complexity of invalid or not, manage the content addressed to the help-text from above to ensure that it displays the right messaging and possesses the right variant.
<sp-field-label for="self">Stay "Positive"</sp-field-label> <sp-textfield multiline id="self" pattern="[P][o][s][i][t][i][v][e]" value="Positive" > <sp-help-text slot="help-text"> Tell us how you are feeling today. </sp-help-text> <sp-help-text slot="negative-help-text">Please be "Positive".</sp-help-text> </sp-textfield>
<sp-field-label for="managed">Stay "Positive"</sp-field-label> <sp-textfield multiline id="managed" pattern="[P][o][s][i][t][i][v][e]" value="Positive" oninput=' const helpText = this.querySelector(`[slot="help-text"]`); helpText.textContent = this.invalid ? `Please be "Positive".` : `Tell us how you are feeling today.`; helpText.variant = this.invalid ? `negative` : `neutral`; ' > <sp-help-text slot="help-text"> Tell us how you're feeling today. </sp-help-text> </sp-textfield>
