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 <option></option>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><option></option></select>
You can also use placeholder to have an extra, non-selectable item with a suggestion. This also allows for not sending any data from a select, when the placeholder is still selected. Making a select field also an optional field in a form. See example 1.
Select values have by default comma separated values when adding to a Template. You can specify a different separator using the argument separator. e.g. separator=";".
All other valid HTML5 attributes are allowed
Example
<p>Select a car:</p>
<div>
<select name="car" placeholder="Choose a car">
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
</select>
</div>
<label for="dino-select">Choose a dinosaur:</label>
<select id="dino-select">
<optgroup label="Theropods">
<option value="Tyrannosaurus">Tyrannosaurus</option>
<option value="Velociraptor">Velociraptor</option>
<option value="Deinonychus">Deinonychus</option>
</optgroup>
<optgroup label="Sauropods">
<option value="Diplodocus">Diplodocus</option>
<option value="Saltasaurus">Saltasaurus</option>
<option value="Apatosaurus">Apatosaurus</option>
</optgroup>
</select>
<select name="Test" selected="C" options="A,B,C,D,E" />
