The six display lines of the 4620 associated with feature buttons are all available for input elements. The top line of the display cannot be used for input.
The input tag causes an automatic line break before and after input text.
Only one input tag can exist per display line.
When a user views a page with the input tag specified, the first thing that shows up in the top line is the card title, if specified. When the user scrolls to the first line containing input, the top line shows the input box title if specified, otherwise the card title is shown. The top line displays the card title for all non-input text.
When the input box is selected, a vertical line (the "cursor") appears at the left side of the input box.
The attribute type password should only be used when it is important to not display the user' s password on the screen. Asterisks will be displayed instead. It is also important that the password not be cached.
The phrase [enter text here] appears for all input tags if the value attribute is null. If the author specifies a non-null content in the value attribute, that content displays between brackets for that input tag.
Only the correct size, type, and number of characters are accepted in to the input box. For example, if alpha text is specified and the user types in a symbol or numeric text, the user input is not accepted. The screen repaints and the user has to re-enter their input. If the wrong kind of text is typed, the user receives an error tone. If the “n” (number) value is specified and the user types in the incorrect number of characters, their input will not be accepted.
