'''Note:''' Programmatically changing the value of one Radio Button in a group using the above technique will not automicatically uncheck the currently checked button (as it would if a user really clicked on it). You must, therefore, remember to progammatically change the ''checked'' status of the other buttons.
== JavaScript HTML Drop-down / Select Object ==
The JavaScript HTML Select object provides a drop down list of choices from which the user can choose (often referred to as ComboBoxes in other GUi GUI environments). When the drop down list is not visible the current selection is displayed in a text area. Due to the fact that the Select Object supports both single and multiple selection of items in the list it is ideal for both "one of many" and "many of many" selection choices.
The Select Object uses the <select> tag together with <option> tags representing the choises to be displayed in the drop-down list:
The optional ''multiple'' attribute may be added to the <select> tag to enable multiple selection of items from the list.
