Input

Input is a text field where users can type their input. Some Input fields allow only numbers, while others are more open-ended. This component is the foundation for many other components which have to do with user input, such as Auto Complete, Date Picker etc.

Basic Usage

<triton-input></triton-input>

<TritonInput/>

<html> 
  <head> 
    <script type="module"> 
      import { defineCustomElements } from '~node_modules/@kognifai/triton-cl-core/loader/index.es2017.js'; 
      defineCustomElements(); 
    </script> 
  </head> 
  <body> 
    <triton-input></triton-input>
  </body> 
</html>

This component follows web standard conventions so any standard props (e.g. placeholder) will be supported.

Variants

Number Input

TritonInput also supports numeric input fields. These fields work similarly to normal ones, but with some extra features to support numbers. To use this kind of input field, set the type property to number.

<triton-input type="number"></triton-input>

Behavior

Step Using Arrow-Keys

A numeric TritonInput has the added feature of up/down arrows to increment or decrement the value. However in some cases an application will need to specify how much the number should change for each up/down click. Use the step property to set the value which will be added or subtracted by each arrow click.

<triton-input type="number" step="100" value="300"></triton-input>

Appearance

Label

A label can be used as a small header for the TritonInput.

<triton-input label="This is the label"></triton-input>

Subtext

There are two options for subtext of an input field. A brief helper-text can be added to help users understand how to use the Input. Alternatively error-text can also be added, to indicate that there is something wrong with the user's input. When both of these are provided, error-text will take presidence.

<triton-input helper-text="This is some helper text" ></triton-input>
<triton-input error-text="This is some error text" ></triton-input>

Required

Use the required property to indicate that the field is mandatory to fill out by the user.

<triton-input required label="Required" placeholder="This field is required"></triton-input>

Icons

Input has two properties for providing icons, leading and trailing positions. These are accessed by the icon-leading and icon-trailing properties.

<triton-input label="Leading Icon" icon-leading="arrow-down"></triton-input>
<triton-input label="Trailing Icon" icon-trailing="arrow-up"></triton-input>
<triton-input label="Leading and Trailing Icon" icon-trailing="arrow-up" icon-leading="arrow-down"></triton-input>
<triton-input label="Loading Icon" icon-leading="loading"></triton-input>

Size

The following sizes are described in the Triton Design System.

small size has a height of 2em and base size has a height of 2.5em

<triton-input size="small" label="Small Size" placeholder="This is a small input"></triton-input>
<triton-input size="base" label="Base Size" placeholder="This is the base sized input"></triton-input>
