3. In the HTML page, multiple selection forms can be used: radio button, check box, select box, and drop-down menu. All of this is useful, but because of the HTML structure, once the coding is completed, it will never go back: the radio button will always be a radio button, the drop-down menu is always a drop-down menu.
XForms is trying to correct this problem by establishing SELECT and SELECT1 element. These elements are the same as the SELECT element in HTML, and also have a list of options.
