implemented a multiselectbox with checkboxes:

Browse Source 
- it looks nearly like a multiple selectbox, eg. scrolls for further lines
- it acts in the same way in forms
- it's NOT identical if using it via javascript

/**
* emulating a multiselectbox using checkboxes
*
* Unfortunaly this is not in all aspects like a multi-selectbox, eg. you cant select options via javascript
* in the same way. Therefor I made it an extra function.
*
* @param string $name string with name of the submitted var which holds the key of the selected item form array
* @param string/array $key key(s) of already selected item(s) from $arr, eg. '1' or '1,2' or array with keys
* @param array $arr array with items to select, eg. $arr = array ( 'y' => 'yes','n' => 'no','m' => 'maybe');
* @param boolean $no_lang NOT run the labels of the options through lang(), default false=use lang()
* @param string $options additional options (e.g. 'width')
* @param int $multiple number of lines for a multiselect, default 3
* @return string to set for a template or to echo into html page
