Hello.

I'm building a custom form and I'd like to use the content_taxonomy_autocomplete_load in one of the form field.

I'm looking for documentation to see if there is some way to make this, but I don't find nothing.

Please can you help me with any suggestion?

====edit===

after debuging a node-form that have the same field I'm trying this code.

<?php
  $form['add']['centrotrabajo'] = array(
    '#type'     => 'content_taxonomy_autocomplete',
    '#title'    => t('Centro de trabajo'),
    '#autocomplete_path' =>'content_taxonomy_autocomplete_value',
    '#vid'      => 9,
    '#required' => TRUE,
    '#delta'    => 0,
    '#field_name' => 'field_medico_centro_trabajo',
    //'#tree'     => TRUE,
    //'#type_name'=>  'medico',
    '#default_value'=> array(),

?>

the poblem is that always say that the field is empty althought I have choose one or two options.

This is the debug from devel when I make a dpm($form_state);

"El campo Centro is required"
