faded-multiselect

A simple skinnable multi-select dropdown for web

Features

An easy to use multi-select dropdown that works out of the box with a simple function invocation.
Can be easily themed for any host application

How to Use

Include faded-multiselect.min.js script file and fade-multiselect.css stylesheet along with jQuery in the HTML page.

Create an HTML multiselect as below:

<select multiple id="select-to-be-tested">
    <option value="option1" selected>Option 1</option>
    <option value="option2">Option 2</option>
    <option value="option3">Option 3</option>
</select>

Instantiate a multiselect dropdown on the select as below:

multiselect = new FadedMultiselect("#select-to-be-tested");

When the HTML select changes (addition or removal of options), just invoke refresh() on the multiselect as

multiselect.refresh();

In order to get an array of selected options, call getValue() on the multi-select as

multiselect.getValue();

When the multi-select is no longer required, call a destroy() on the multi-select and the original multi-select will be brought back on the page.

multiselect.destroy();

Options

For an internal Select All and Unselect All option, initialize the multi-select as

multiselect = new FadedMultiselect("#select-to-be-tested", {
    allOption: true
});

To be notified on every value change, supply a function to be invoked on every state change as shown below

multiselect = new FadedMultiselect("#select-to-be-tested", {
    onStateChange: function (value, item) {
        // Use 'value' to track the current selection
        // Use 'item' to track the currently toggled item
    }
});

To set a custom dropdown button text, supply a function that returns the button text on a particular selection as shown below

multiselect = new FadedMultiselect("#select-to-be-tested", {
    buttonText: function (value) {
        // Use 'value' to get an array of selection in the dropdown
    }
});

To limit the dropdown height, supply maxDropdownHeight and a skinnable scrollbar will be used within the dropdown

multiselect = new FadedMultiselect("#select-to-be-tested", {
    maxDropdownHeight: 200
});
