+
+Creates a generic input tag or textarea tag, depending on content size. The
+mount of desired rows must be given with C<rows> parameter, Accpeted parameters
+include C<min_rows> for rendering a minimum of rows if a textarea is displayed.
+
+You can force input by setting rows to 1, and you can force textarea by setting
+rows to anything >1.
+
+=item C<multiselect2side $id, %params>
+
+Creates a JavaScript snippet calling the jQuery function
+C<multiselect2side> on the select control with the ID C<$id>. The
+select itself is not created. C<%params> can contain the following
+entries:
+
+=over 2
+
+=item C<labelsx>
+
+The label of the list of available options. Defaults to the
+translation of 'Available'.
+
+=item C<labeldx>
+
+The label of the list of selected options. Defaults to the
+translation of 'Selected'.
+
+=back
+
+=item C<sortable_element $selector, %params>
+
+Makes the children of the DOM element C<$selector> (a jQuery selector)
+sortable with the I<jQuery UI Selectable> library. The children can be
+dragged & dropped around. After dropping an element an URL can be
+postet to with the element IDs of the sorted children.
+
+If this is used then the JavaScript file C<js/jquery-ui.js> must be
+included manually as well as it isn't loaded via C<$::form-gt;header>.
+
+C<%params> can contain the following entries:
+
+=over 2
+
+=item C<url>
+
+The URL to POST an AJAX request to after a dragged element has been
+dropped. The AJAX request's return value is ignored. If given then
+C<$params{with}> must be given as well.
+
+=item C<with>
+
+A string that is interpreted as the prefix of the children's ID. Upon
+POSTing the result each child whose ID starts with C<$params{with}> is
+considered. The prefix and the following "_" is removed from the
+ID. The remaining parts of the IDs of those children are posted as a
+single array parameter. The array parameter's name is either
+C<$params{as}> or, missing that, C<$params{with}>.
+
+=item C<as>
+
+Sets the POST parameter name for AJAX request after dropping an
+element (see C<$params{with}>).
+
+=item C<handle>
+
+An optional jQuery selector specifying which part of the child element
+is dragable. If the parameter is not given then it defaults to
+C<.dragdrop> matching DOM elements with the class C<dragdrop>.  If the
+parameter is set and empty then the whole child element is dragable,
+and clicks through to underlying elements like inputs or links might
+not work.
+
+=item C<dont_recolor>
+
+If trueish then the children will not be recolored. The default is to
+recolor the children by setting the class C<listrow0> on odd and
+C<listrow1> on even entries.

+                        recolor_rows => 1) %]
+
+After dropping e.g. the third element at the top of the list a POST
+request would be made to the C<reorder> action of the C<SystemThings>
+controller with a single parameter called C<thing_ids> -- an array
+containing the values C<[ 6, 2, 15 ]>.

+=item C<dump REF>

+In addition to pure keys/method you can also provide coderefs as I<value_sub>
+and/or I<title_sub>. If present, these take precedence over keys or methods,

 If the option C<with_empty> is set then an empty element (value
 C<undef>) will be used as the first element. The title to display for
 this element can be set with the option C<empty_title> and defaults to
 an empty string.
