CALL INFORMATION

Parameters: name value multiple

Positional parameters in same order.

Pass attribute hash as last to subroutine: no

Must pass named parameter interpolate=1 to cause interpolation.

Invalidates cache: YES

Called Routine:

ASP/perl tag calls:

    $Tag->selected(
        {
         name => VALUE,
         value => VALUE,
         multiple => VALUE,
        }
    )
  
 OR
 
    $Tag->selected($name, $value, $multiple);

DESCRIPTION

You can provide a ``memory'' for drop-down menus, radio buttons, and checkboxes with the [checked] and [selected] tags.

This will output SELECTED if the variable var_name is equal to value. If the optional MULTIPLE argument is present, it will look for any of a variety of values. Not case sensitive.

Here is a drop-down menu that remembers an item-modifier color selection:

    <SELECT NAME="color">
    <OPTION [selected color blue]> Blue
    <OPTION [selected color green]> Green
    <OPTION [selected color red]> Red
    </SELECT>

Here is the same thing, but for a shopping-basket color selection

    <SELECT NAME="[modifier-name color]">
    <OPTION [selected [modifier-name color] blue]> Blue
    <OPTION [selected [modifier-name color] green]> Green
    <OPTION [selected [modifier-name color] red]> Red
    </SELECT>
