select tag
The select tag, which, when implemented in the code, is written like this - <select>, is an HTML tag that belongs to forms and input tags. Form and Input HTML tags are used to create interactive website elements, hence the name of the category. It includes object such as HTML drop-downs, buttons etc.
<select> is used to create a drop-down list. The <option> tags inside the <select> element define the available options in the list. This tag is supported in the current version of HTML, which is HTML5.

Attributes and values
An attribute is a piece of additional information about a tag. While tags denote the type of objects they mark or create, attributes set the parameters of these objects. These parameters can include anything from the types of possible interactions to its visual style to its actual contents.
Values indicate how a certain attribute is actually implemented, if there is a number of ways it can happen.
What attributes are actually allowed in a certain tag depends on the tag itself. Much like possible attributes depend on a tag, possible values depend on an attribute.
The <select> tag supports the following attributes (with their respective values):
| Attribute | Value | Description |
|---|---|---|
| autofocus | autofocus | Specifies that the drop-down list should automatically get focus when the page loads |
| disabled | disabled | Specifies that a drop-down list should be disabled |
| form | form_id | Defines one or more forms the select field belongs to |
| multiple | multiple | Specifies that multiple options can be selected at once |
| name | name | Defines a name for the drop-down list |
| required | required | Specifies that the user is required to select a value before submitting the form |
| size | number | Defines the number of visible options in a drop-down list |
Global Attributes
Global attributes are HTML tag attributes that can be used by any tag, hence the name "global". They are in contrast to unique attributes that are tag-specific.
<select> supports global attributes.
Event Attributes
Event attributes are HTML tag attributes that allow triggering actions upon specific conditions, hence the name "event". Other types of attributes, namely global and unique attributes, can also trigger actions, but the difference is that even attributes allow calling scripts, such as JavaScript functions, while most other attributes only support a certain type of action.
<select> supports event attributes.
