SELECT tag defines a selection list on an HTML form. A selection list displays a list of options
from which the user can select an item. If the MULTIPLE attribute is supplied, users can select
multiple options from the list at a time. If the MULTIPLE attribute is not supplied users can select
only one option in the list at a time.The
SIZE attribute specifies how many options in the list are displayed at one time. For
multiple-selection lists, if you do not specify the SIZE attribute, the browser displays some, maybe all,
of the options. For single-selection lists, the browser displays the list as a drop-down menu
that initially shows only one option. The user can click the list to display the rest of the options. If you
specify the SIZE attribute, the list is displayed as a scrolling list that shows the specified number of
options, regardless of whether the list allows single or multiple selection.When the form containing the selection list is submitted to the server, a name/value pair is sent for each selected option in the list.
The
SELECT tag should be used between <FORM> and </FORM> tags. Similarly, the <OPTION> tags would be used inside the <SELECT> tags.<SELECT NAME="selectName" MULTIPLE ONBLUR="JScode" ONCHANGE="JScode" ONCLICK="JScode" ONFOCUS="JScode" SIZE="listLength">....</SELECT>NAME specifies the name of the select element. This value is the name portion of the name/value pair sent to the invoked CGI program when the form is submitted. The name
is not displayed on the form.MULTIPLE specifies that multiple items can be selected. If this attribute is omitted, only one item can be selected from the list. If multiple selection is enabled, the user usually needs to hold down the Shift key to select additional items.ONBLUR specifies JavaScript code to execute when the select element loses focus.ONCHANGE specifies JavaScript code to execute when the select element loses focus and its value has been modified.ONCLICK specifies JavaScript code to execute when a user clicks an item in the list.ONFOCUS specifies JavaScript code to execute when the element gets focus.SIZE specifies the number of options visible when the form is displayed. If the list contains more options than specified by size, the list is displayed with scrollbars.
