# Theming capabilities - JavaScript Date & Time demo

Javascript Date and time scroller with iOS, Material, Windows look & feel. Customize colors and styling with theme builder. Plain JS api for usage everywhere.

## Description

The look and feel of the date picker can be deeply customized. There are four levels of customization:

- **Base themes:** Choose between **iOS**, **Material** and **Windows**.
- **Light or dark:** Every theme has a `light` and `dark` variant. Setting the `themeVariant` to `'auto'` will switch based on system settings.
- **Custom themes:** Use the [theme builder](https://mobiscroll.com/themebuilder) to customize the colors and make it match your brand.
- **Custom CSS:** If you need further customization, the sky is the limit with CSS overrides.

You can also see how every example looks by changing the theme from the header.

## What this demo shows

- An inline wheel-style date picker is shown alongside theme controls so you can preview different date picker looks in the same layout.
- **Theme controls** A segmented picker lets you switch between the `iOS`, `Material`, and `Windows` base themes, with `iOS` selected by default.
- **Theme variant** A dark-theme switch is enabled by default, showing how the same date picker can be previewed in a dark variant.
- **Custom theme option** A separate switch for theme builder or Sass-based customization is present but turned off by default.
- **Inline date picker** The example embeds the picker directly in the page without an input by using inline display mode.
- **Date selection** Separate scrollable wheels let users select the month, day, and year. The selected values appear in a central selection area, while neighboring values remain visually subdued.
- **Scrolling behavior** Users can scroll vertically through neighboring values to move between dates, including dates in other months or years.

## Best for

- **Theme comparison** Evaluating how the same date picker looks with the `iOS`, `Material`, and `Windows` base themes.
- **Light and dark mode previewing** Checking how a date picker setup behaves across light and dark theme variants.
- **Branded calendar experiences** Exploring how a base theme can be extended with theme builder, Sass, or custom CSS to match a product's visual style.

## Tutorial

### Pick a base theme

- (x) iOS
- ( ) Material
- ( ) Windows

### Then choose between light or dark theme variant

- [ ] Turn dark theme on

### Or build a custom theme based on any base theme

- [ ] Use the [theme builder](https://mobiscroll.com/themebuilder) or [Sass](https://mobiscroll.com/docs/javascript/datepicker/css-variables) to customize themes

```js
theme: 'ios',
themeVariant: 'light'
```

With "Material":

```js
theme: 'material',
themeVariant: 'light'
```

With "Windows":

```js
theme: 'windows',
themeVariant: 'light'
```

## API used in this demo

- [`controls`](https://mobiscroll.com/docs/javascript/datepicker/api#opt-controls) - option
- [`display`](https://mobiscroll.com/docs/javascript/datepicker/api#opt-display) - option
- [`theme`](https://mobiscroll.com/docs/javascript/datepicker/api#opt-theme) - option
- [`themeVariant`](https://mobiscroll.com/docs/javascript/datepicker/api#opt-themeVariant) - option

## Code

### JS

```js
mobiscroll.datepicker('#demo', {
  controls: ['date'],
  display: 'inline',
  theme: 'material', // Can be 'ios', 'material', 'windows' or 'auto' - in case of 'auto', the theme will automatically be set based on the platform
  themeVariant: 'dark', // Can be 'light', 'dark' or 'auto' - in case of 'auto' it is set based in the active system theme
});
```

### HTML

```html
<div id="demo"></div>
```

## Implementation notes

- Use `controls: ['date']` and `display: 'inline'` - despite living under the `datetime` view, this demo's live instance is a date-only wheel picker (no time or datetime controls are used).
- Set `theme` to `'ios'`, `'material'`, or `'windows'` to pick the base theme.
- Set `themeVariant` to `'light'` or `'dark'` to switch the variant within the chosen base theme.
- `theme` and `themeVariant` can be updated at runtime via `setOptions({ theme })` / `setOptions({ themeVariant })` on the same live picker instance rather than re-initializing it.
- `theme` also accepts a custom-named theme (e.g. `'material-indigo'`, `'windows-yellow'`, `'ios-gray'`) built on top of a base theme, settable via `setOptions({ theme: customName })`; a custom theme name already encodes its own light/dark variant, so `themeVariant` does not need to be set alongside it.
