{html_options} es una
|
|
<link linkend="language.custom.functions">función customizada</link>
|
|
que crea un grupo html <select><option> con los datos proporcionados.
|
|
Este se encarga de cuidar cuales datos han sido selecionado por default.
|
|
Los atributos son valores y salidas, a menos que usted utilice
|
|
options en lugar de eso.
|
|
</para>
|
|
<para>
|
|
Si un valor es una matriz, este será tratado como un <optgroup> html,
|
|
y mostrara los grupos. La recursión es soportada por <optgroup>.
|
|
Todas las salidas son compatibles con XHTML.
|
|
</para>
|
|
<para>
|
|
Si el atributo opcional <emphasis>name</emphasis> es dado, las
|
|
etiquetas <select name="groupname"></select>
|
|
encapsularan la lista de opciones.
|
|
De otra manera solo es generada la lista de opciones.
|
|
</para>
|
|
<para>
|
|
Todos los parámetros que no estan en la lista de arriba son
|
|
exibidos como name/value-pairs dentro de las etiquetas <select>.
|
|
Estas son ignoradas si la opcion <emphasis>name</emphasis> no es dada.
