Dropdown

The dropdown component uses the HTML select element and adds custom styling and additional functionality.

The following example will create a simple dropdown with a label.

<Dropdown label="Choose one">
  <option value="1">Option 1</option>
  <option value="2">Option 2</option>
  <option value="3">Option 3</option>
</Dropdown>

Value binding

Controlled component

The dropdown can be used as a controlled component by providing the value and the onChange props.

const App = () => {
    const [selectValue, setSelectValue] = useState();
    
    return <Dropdown label="Choose one" value={selectValue} onChange={setSelectValue}>
      <option value="" />
      <option value="1">Option 1</option>
      <option value="2">Option 2</option>
      <option value="3">Option 3</option>
    </Dropdown>;
}

Uncontrolled component

When using the Dropdown as an uncontrolled component, a ref prop can be used to have a reference to the component where you can access the underlying selectNode

const App = () => {
    const myRef = useRef(null);
    const saveChanges = () => {
        const select = myRef.current.selectNode;
        console.log(select.options[select.selectedIndex].value); // get the selected value 
    }; 
    
    return <div className="App">
        <Dropdown ref={myRef} label="Choose one">
          <option value="1">Option 1</option>
          <option value="2">Option 2</option>
          <option value="3">Option 3</option>
        </Dropdown>
        <Button onClick={saveChanges}>Save the changes</Button>  
    </div>;
}

Options

const handler = (ev) => { setState(ev.target.checked) }
<Input onChange={handler} />

Customizing the appearance

While the provided pre-built themes are enough in many use cases, most of the times on top of adapting to a specific platform, you'd also like to match a brand or color scheme. Mobiscroll provides various ways to achieve this:

• Create custom themes using the theme builder - the custom themes can be also built using out theme builder, on a graphical user interface, without any coding, or the need for Sass support in your project.
• Create custom themes using Sass - use this, if you need multiple themes with different color variatons, in case you have pages with different colors, or you'd like to users to customize the colors of your app.
• Override the Sass color variables - the straightforward way to change the colors in one place throughout the application.

Override the Sass Color Variables

A convenient way to customize the colors of the Mobiscroll components is to override the Sass color variables.

Let's say your branding uses a nice red accent color, and you'd like that color to appear on the Mobiscroll components as well, while still using platform specific themes (e.g. ios on iOS devices, material on Android devices, and mobiscroll on desktop). You can override the accent color for every theme:

$mbsc-ios-accent: #e61d2a;
$mbsc-material-accent: #e61d2a;
$mbsc-mobiscroll-accent: #e61d2a;

@import "~@mobiscroll/React/dist/css/mobiscroll.react.scss"

You can also customize the colors on many levels:

1. Theme specific variables (ex. $mbsc-material-background, $mbsc-ios-dark-text) are applied to all components in a theme. Complete list of variables here.
2. Component specific global variables (ex. $mbsc-card-background-light, $mbsc-listview-text-dark) are applied to all themes for a specific component.
3. Component and theme specific variables (ex. $mbsc-ios-dark-form-background, $mbsc-material-input-text) are applied to a specific theme and a specific component.
