Dropdown

The Dropdown component can be used for collecting user provided information from a set of options. It uses the HTML select element and adds custom styling and additional functionality.

Usage​

Use the label option to provide a label to the dropdown.

All the options can be passed to the dropdown via data- attributes with one exception. The exception is the disabled attribute, that don't need the data- prefix, since the native select supports it.

<label>
    <select data-label="Choose one" mbsc-dropdown id="choose">
        <option>Option 1</option>
        <option>Option 2</option>
        <option>Option 3</option>
    </select>
</label>

Auto vs. manual initialization​

If the component is added later to the DOM, e.g. with an AJAX page load, a custom function named enhance needs to be called in order to initialize the dynamically added component. When the enhance function is called on a DOM element, all form elements will be initialized inside this element.

var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function() {
    if (xhr.readyState == XMLHttpRequest.DONE) {
        var page = document.getElementById('page');
        page.innerHTML = xhr.responseText;
        mobiscroll.enhance(page);
    }
}
xhr.open('GET', '/myform', true);
xhr.send();
