<H1><A NAME="description">DESCRIPTION</A></H1>
<P>This module implements an HTML widget with multiple layers.  Only one layer
is visible at any given time, controlled by a &lt;SELECT&gt; box.  For an
example see <A HREF="http://www.420.am/selectlayers/">http://www.420.am/selectlayers/</A></P>
<P>This HTML generated by this module uses JavaScript, but nevertheless attempts
to be as cross-browser as possible.  The 0.05 release drops Navigator 4
compatibility and has been tested under Mozilla Firefox 1.0.6, MSIE 6.0, 
Konqueror 3.3.2, and Opera 8.0.2.</P>
<P>
<HR>
<H1><A NAME="forms">FORMS</A></H1>
<P>Not all browsers seem happy with forms that span layers.  The generated HTML
will have a &lt;/FORM&gt; tag before the layers and will generate
&lt;FORM&gt; and &lt;/FORM&gt; tags for each layer.  To facilitate
&lt;SUBMIT&gt; buttons located within the layers, you can pass a form name
and element names, and the relevant values will be copied to the layer's form.
See the <STRONG>form_</STRONG> options below.</P>

<DT><STRONG><A NAME="item_new_KEY%2C_VALUE%2C_KEY%2C_VALUE%2E%2E%2E">new KEY, VALUE, KEY, VALUE...</A></STRONG><BR>
<DD>
Options are passed as name/value pairs:
<P>options - Hash reference of layers and labels for the &lt;SELECT&gt;.  See
          <A HREF="http://search.cpan.org/doc/GSAR/Tie-IxHash-1.21/lib/Tie/IxHash.pm">the Tie::IxHash manpage</A> to control ordering.
          In HTML: &lt;OPTION VALUE=``$layer''&gt;$label&lt;/OPTION&gt;</P>
<P>layer_callback - subroutine reference to create each layer.  The layer name
                 is passed as an option in <EM>@_</EM></P>
<P>selected_layer - (optional) initially selected layer</P>
<P>form_name - (optional) Form name to copy values from.  If not supplied, no
            values will be copied.</P>
<P>form_action - Form action</P>
<P>form_text - (optional) Array reference of text (or hidden) form fields to copy
            from the <STRONG>form_name</STRONG> form.</P>
<P>form_checkbox - (optional) Array reference of checkbox form fields to copy from
                the <STRONG>form_name</STRONG> form.</P>
<P>fixup_callback - (optional) subroutine reference, returns supplimentary
                 JavaScript for the function described above under FORMS.</P>
<P>#form_select</P>
<P>size - (optional) size of the &lt;SELECT&gt;, default 1.</P>
<P>unique_key - (optional) prepended to all JavaScript function/variable/object
             names to avoid namespace collisions.</P>
<P>html_beween - (optional) HTML between the &lt;SELECT&gt; and the layers.</P>
<P></P>
<DT><STRONG><A NAME="item_html">html</A></STRONG><BR>
