The options inside a selection menu are what the user will be selection. The normal syntax for an option is as follows:
However, it's important to note that the text inside the
<option> element itself is not always used, and essentially becomes the default value for attributes which are not specified.
The attributes which control the actual appearance and function of the option are
label. The label represents the text which will be displayed in the drop-down menu (what you're looking at and will click on to select it). The value represents the text which will be sent along with form submission. If either of these values is omitted, it uses the text inside the element as the value instead. So the example we gave above could be "expanded" to this:
<option label="Some Option" value="Some Option">
Note the omission of the inside text and end tag, which are not required to actually construct an option inside the menu. If they were included, the inside text would be ignored because both attributes are already specified and the text is not needed. However, you probably won't see a lot of people writing them this way. The most common way it's written is with a value that will be sent to the server, along with the inside text which eventually becomes the label attribute, like so:
<option value="option1">Some Option</option>
You can also specify a certain option to be selected in the menu by default by attaching the
selected attribute to it. By default, if no option is specified as selected in the menu, the first option in the menu will be selected when rendered. If more than one option has the
selected attribute attached, then the last option present in the menu with the attribute will be the one selected by default.
<option value="option1" selected>Some option</option>
If you're using the attribute in a multi-option selection menu, then all the options with the attribute will be selected by default, and none will be selected if no options have the attribute.
<select multiple> <option value="option1" selected>Some option</option> <option value="option2" selected>Some option</option> </select>
