Picky ☜

Yet another React select list.

Motivation

When dealing with medium+ length select lists, especially multi-select lists. The common approach is to use tags e.g.

!Tag List

Source: React-Select by Jed Watson

This approach is fine for smaller lists. When you have options for 20, 30, 100+ options that the use can select, it becomes unmanigable.

For example you have a internal staff mailing list. You want to mail all staff in a department (30 employees). You select all. That would be 30 tags taking unneccessary space.

This is a multiselect with checkboxes, a select all option, and a filter. Along a similar vein as David Stutz's Bootstrap Multiselect. There is a port of that library to react with Skratchdot's React Bootstrap Multiselect. However I don't want a dependency on jQuery. If you are already using jQuery that might be an alternative for you.

If you like the tag list like React-Select, then that would be a great option for you. It's a really great, well-tested library. Give it a look.

You can also achieve the same result with a great deal of flexibility using Paypal's Downshift.

- placeholder - Default message when no items are selected.
- value - The selected value(s), array if multiple is true. Not needed if using as an uncontolled component
- numberDisplayed - Then number of selected options displayed until it turns into '(selected count) selected'.
- multiple - Set to true for a multiselect, defaults to false.
- options - Array of possible options.
- onChange - Called whenever selected value(s) have changed. Pass the selected value back into value.
- open - Can open or close the dropdown manually. Defaults to false.
- includeSelectAll - If set to true will add a Select All checkbox at the top of the list.
- includeFilter - If set to true will add an input at the top of the dropdown for filtering the results.
- filterDebounce - Debounce timeout, used to limit the rate the internal onFilterChange gets called. Defaults to 150ms.
- dropdownHeight - The height of the dropdown. Defaults to 300px.
- onFiltered - Called after a filter has been done with the filtered options.
- onOpen - Called after the dropdown has opened.
- onClose - Called after the dropdown has closed.
- valueKey - If supplying an array of objects as options, this is required. It's used to identify which property on the object is the value.
- labelKey - If supplying an array of objects as options, this is required. It's used to identify which property on the object is the label.
- render - Used for custom rendering of items in the dropdown. More info below.
- tabIndex - Pass tabIndex to component for accessibility. Defaults to 0
- keepOpen - Default true. Single selects close automatically when selecting a value unless this is set to true.
- manySelectedPlaceholder - Default "%s selected" where %s is the number of items selected. This gets used when the number if items selected is more than the numberDisplayed prop and when all options are not selected.
- allSelectedPlaceholder - Default "%s selected" where %s is the number of items selected. This gets used when all options are selected.
- selectAllText - Default "Select all", use this to override "Select all" text from top of dropdown when included with includeSelectAll.
- renderSelectAll - Used for rendering a custom select all
- defaultFocusFilter - If set to true, will focus the filter by default when opened.
- renderList - Render prop for whole list, you can use this to add virtualization/windowing if necessary
- filterPlaceholder - Override the filter placeholder. Defaults to 'Filter...'

Custom rendering

$3

You can render out custom items for the dropdown.

Example

`javascript
value={this.state.arrayValue}
options={bigList}
onChange={this.selectMultipleOption}
open={false}
valueKey="id"
labelKey="name"
multiple={true}
includeSelectAll={true}
includeFilter={true}
dropdownHeight={600}
render={({
style,
isSelected,
item,
selectValue,
labelKey,
valueKey,
multiple,
}) => {
return (
style={style} // required
className={isSelected ? 'selected' : ''} // required to indicate is selected
key={item[valueKey]} // required
onClick={() => selectValue(item)}
>
{/ required to select item /}

{item[labelKey]}

);
}}
/>
`

The render callback gets called with the following properties:
style, isSelected, item, labelKey, valueKey, selectValue, multiple

- isSelected - boolean - true if item is selected. Use this for styling accordingly.
- item - object | number | string - The item to render.
- labelKey - Used to get the label if item is an object
- valueKey - Used to get the value if item is an object, good for keys.
- selectValue - function(item) - Selects the item on click
- multiple - boolean - Indicates if is a multiselect.

Note

- If your rendered item affects the height of the item in anyway. Supply itemHeight to Picky.
- If you wish to show a radio button or a checkbox, be sure to add readOnly prop to the input.
