Zend + Using names with brackets (array notation) in FormSelect view helper rendered as multiple select element, not a regular dropdown

Question

In my project, I am required to have many drop-down fields with array-notated names, like so:

<select name="language[]">...</select>
<select name="language[]">...</select>
<select name="language[]">...</select>

Since I need to render Zend's formSelect view helper for it, I thought it was as simple as doing:

for($i = 0; $i < 3; $++){
    echo $this->formSelect('language[]', $this->languages[$i],
                                         $this->attribs[$i],
                                         $this->languageOptions[$i]);
}

But I was wrong: Instead of rendering them as regular drop-down fields, Zend decides to be a smarty-pant and render them as multiple-select fields, instead.

I understand the thinking behind this behavior, but it just so happens that it the help formSelect provides is too much for my needs.

Now, I can amend it with using JavaScript to remove the multiple="multiple" attribute to transform them to regular drop-downs...

But out of curiosity, is there a way to make formSelect render these elements as regular drop-down fields, other than modifying its underlying code?

You are correct, the formSelect helper is deciding to make it a multi-select based on the fact that the element name is an array[].

You can override the behavior however.

To do so, add multiple => false to your list of $attribs for the element.

E.g.

$attribs = array('multiple' => false, 'class' => 'selection');
echo $this->formSelect('not_array[]', '', $attribs, $options);

This should prevent it from trying to make the element support more than one selection.
