73 <b>new_ml_form_select</b> creates a new form select box
74 input widget. The form into which this widget is being
75 embedded is passed as the <b>form</b> parameter. The select
76 box is created with no options, in drop-down mode (size 0),
77 single choice (multiple 0).</td></table>

83 <b>ml_form_select_(set|get)_size</b> sets the size (number
84 of rows) in the select box. If the size is 0, then the
85 select box will be rendered as a drop-down menu. If the size
86 is > 0, then the select box will be rendered as a

93 <b>ml_form_select_(set|get)_multiple</b> sets the multiple

103 To add options to the select box, use the
104 <b>ml_form_select_push_back</b> and other access functions.
105 These are modelled on the c2lib <b>vector_*</b>
106 functions.</td></table>

112 To choose which option is selected first in a single
113 selection select box, call
114 <b>ml_form_select_set_selection</b>. For select boxes which
115 allow multiple selections, prepare a <b>vector</b> of
116 <b>int</b> which is at least as long as the number of
117 options. Each element of the vector should be a boolean
118 value saying whether the corresponding option is selected or
120 <b>ml_form_select_set_selections</b>.</td></table>

126 If the select box allows only single selections, then after
127 the form has been submitted by the user, you can read back
128 the index of the option which was selected using
129 <b>ml_form_select_get_selection</b>. This returns -1 if
130 nothing was selected.</td></table>

136 If the select box allows multiple selections, then call
137 <b>ml_form_select_get_selections</b> which returns a vector
138 of boolean values (<b>vector</b> of <b>int</b>) of exactly
139 the same length as the number of options. This vector will
140 contain true corresponding to every selected option. This
141 function may also return <b>NULL</b>, indicating that
142 nothing was selected (or the form wasn't
143 submitted).</td></table>
