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>
