Set of enhancements for input control

The intention of creating this library was to bring input component out of the dropdown/autocomplete/whatever code, so it could be easily replaced with your custom component, and also to split independent functionality into different components, which could be combined with each other (still not quite sure it was worth it, though).

There are currently four components:

1. <Autosize />
2. <Autocomplete />
3. <Dropdown />
4. <Mask />
5. <DatePicker />

All components accept function as a child, providing props as a first argument, which you should pass to your input component. If there is nothing else except input, it could be passed as a child directly (for simplicity).

<Combobox /> is a combination of Dropdown, Autosize and/or Autocomplete components.

Autosize

Autosize resizes component to fit it's content.

<Autosize defaultValue={value}
          minWidth={100}>
  {(inputProps, { width }) =>
    <input type='text' {...inputProps} />
  }
</Autosize>

Autosize Props

• value string - Input value (for a controlled component)
• defaultValue string - Initial value (for a uncontrolled component)
• getInputElement function() - Optional callback that provides input DOM element
• defaultWidth number - Minimum input width

Autocomplete

Autocomplete prompts a value based on provided options (see also react-autocomplete for the same behaviour)

<Autocomplete defaultValue={value}
              options={options}>
  {(inputProps, { matchingText, value }) =>
    <input type='text' {...inputProps} />
  }
</Autocomplete>

Autocomplete Props

• value string - Input value (for a controlled component)
• defaultValue string - Initial value (for a uncontrolled component)
• getInputElement function - Optional callback that provides input DOM element
• options array - Array of options that are used to predict a value

options is an array of strings or objects with a text or value string properties.

Dropdown

Dropdown shows a dropdown with a (optionally filtered) list of suitable options.

<Dropdown defaultValue={value}
          options={options}>
  {(inputProps, { textValue }) =>
    <input type='text' {...inputProps} />
  }
</Dropdown>

Dropdown Props

• value string - Input value (for a controlled component)
• defaultValue string - Initial value (for a uncontrolled component)
• options array - Array of shown options
• onRenderOption function(className, style, option) - Renders option in list
• onRenderCaret function(className, style, isActive, children) - Renders a caret
• onRenderList function(className, style, isActive, listShown, children, header) - Renders list of options
• onRenderListHeader function(allCount, shownCount, staticCount) - Renders list header
• dropdownClassName string - Dropdown root element class name
• dropdownProps object - Custom props passed to dropdown root element
• optionFilters array - List of option filters

options is an array of strings or objects with a shape:

• value - "real" value of on option
• text - text used as input value when option is selected
• label - text or component rendered in list
• static - option is never filtered out or sorted
• disabled - option is not selectable

null option is rendered as a separator

optionFilters is an array of filters for options (for convenience). By default, these filters are used:

• filters.filterByMatchingTextWithThreshold(20) - filters options by matching value, if options length is more than 20
• filters.sortByMatchingText - sorting by matching value
• filters.limitBy(100) - cuts options longer than 100
• filters.notFoundMessage('No matches found') - shows option with 'No matches found' label if all options are filtered out
• filters.filterRedudantSeparators - removes redudant separators (duplicated or at the begin/end of the list)

Mask

Mask formats input value.

<Mask defaultValue={value}
      pattern='0000-0000-0000-0000'>
  {(inputProps, { value }) =>
    <input type='text' {...inputProps} />
  }
</Mask>

Mask Props

• value string - Input value (for a controlled component)
• defaultValue string - Initial value (for a uncontrolled component)
• getInputElement function() - Optional callback that provides input DOM element
• pattern string - String formatting pattern. Only '0' (digit) or 'a' (letter) pattern chars are currently supported.
• emptyChar string - Character used as an empty symbol (' ' by default)
• placeholder string - If set, it is shown when unmaskedValue is empty
• onUnmaskedValueChange function(text) - Fires when value is changed, providing unmasked value

DatePicker

DatePicker uses Mask to format date and shows calendar (react-date-picker by default) in popup.

<DatePicker defaultValue={moment(value).format('ddd DD/MM/YYYY')}
            placeholder={moment().format('ddd DD/MM/YYYY')}
            pattern='ddd DD/MM/YYYY'
            locale='en'>
  {(inputProps, { value }) =>
    <input type='text' {...inputProps} />
  }
</DatePicker>

DatePicker Props

• value string - Input value (for a controlled component)
• defaultValue string - Initial value (for a uncontrolled component)
• pattern string - Date formatting pattern. For now, only these tokens are supported:
  • DD - day of month
  • MM - month
  • YYYY - year
  • ddd - day of week (not editable)
• placeholder string - If set, it is shown when unmaskedValue is empty
• locale string - Date locale
• onRenderCalendar function(className, style, date, isActive, popupShown, onSelect, locale) - Returns calendar component shown in popup (react-date-picker by default)
• onChange function(date) - Fires when date is selected, providing moment.js object

Combobox

Combobox combines Dropdown, Autosize and/or Autocomplete components.

<Combobox defaultValue={value}
          options={options}
          autosize
          autocomplete>
  {(inputProps, { matchingText, width }) =>
    <input type='text' {...inputProps} />
  }
</Combobox>

Autosize and Autocomlete are enabled with corresponding bool props, other properties are proxied to Dropdown component.

See demo for code examples.
