       name

       values

       options

       Gives the options as an array ref that should be displayed to the user.  If no options are
       given, the values from values are used.

       rows

       If specified a select box is display with the given number of lines.  If not specified or
       undef, a drop down list is shown.

       addtop

       Array ref which contains items that should be added at the top of the select box. Each
       item consists of an array ref with two entries, the first is the value and the second is
       the option that is displayed on the page. If the second is missing the value (first
       entry)is displayed. Example:

           addtop => [ [1 => 'first item'], [2 => 'second item']]

       addbottom

       Array ref which contains items that should be added at the bottom of the select box. Each
       item consists of an array ref with two entries, the first is the value and the second is
       the option that is displayed on the page. If the second is missing the value (first
       entry)is displayed. Example:

           addbottom => [ [9999 => 'last item'], [9999 => 'very last item']]

       filter

       If given, only items where the value matches the regex given in "filter" are displayed.

       showurl

       This URL will be requested if the user clicks on SHOW in the popup or double clicks the
       control. The value of the selected option will be appended to that url. Should be
       something like '/foo/bar.epl?id='.  NOTE: This URL is not encoded in anyway, so make sure
       it is properly url encoded.

       datasrcurl

       This URL will be requested when the user types any input to request the data for the
       control. The characters the users has typed will be passed by the parameter query and the
       name of the datasrc attribute will be passed in the datasrc parameter.  NOTE: This URL is
       not encoded in anyway, so make sure it is properly url encoded.

       show_on_select

       If true show the selected item as soon as it is selected (useses showurl)

       use_ajax

       If set to an id of an html element, documents that are loaded via showurl are fetch via
       ajax into this html container, instead of fetching a whole page.

       $fdat{-init-<name>}

       If set this value is used to prefill the input box, if not set get_values method of the
       datasource object is call, which might be take a long time in case of many options.
