Synopsis

How to use select with option fields to create a dropdown input

Description

The select element is used to create a drop-down list.

The name attribute is needed to reference the form data after the form is submitted (if you omit the name attribute, no data from the drop-down list will be submitted).

The id attribute is needed to associate the drop-down list with a label.

The <input type="option"></input>tags inside the <select> element define the available options in the drop-down list.

Instead of option inputs, it's also possible to use selected and options as attributes of the select element. In this case options should contain a comma-separated list of options and selected can be used to specify which option should be selected.

Parameters

<select><input type="option"></input></select>

All other valid HTML5 attributes are allowed

Example

<p>Select a car:</p>
<div>
    <select name="car">
		<input type="option" value="volvo">Volvo</input>
		<input type="option" value="saab">Saab</input>
    </select>
</div>
