>>> [!note] Migrated issue <!-- Drupal.org comment --> <!-- Migrated from issue #1522456. --> Reported by: [rodrigo panchiniak fernandes](https://www.drupal.org/user/411448) >>> <p><strong>Description</strong><br> How many times have you visited a website where an option would reveal itself unavailable only after the page was submitted? It is said a monk fails to become priest every time a website behaves like that. It is a big concern on usability the showing of options that are indeed forbidden to the current user, and this module exorcises part of the manifestations of such evil.</p> <p><strong>Objective</strong><br> <a href="http://drupal.org/sandbox/panchiniak/1521136" title="Sandbox">Tefiltro</a> module improves the usability of your Drupal 7 website through a process of term filtering. It hides from the "options list" of a "term reference" field, those options the visitor will not be able to choose under certain scenarios (<em>Vide</em> Scenario bellow).<br> It hides the options that represent terms not referenced at nodes authored by: </p> <ul> <li>current user <code>OR</code></li> <li>members of the oldest organic group owned by current user.</li> </ul> <p><strong>Scenario</strong><br> <em>Visitor</em> wants to choose driving (node drive) some of his several cars (node car) according to their colors (vocabulary color). Each car has a term reference to a color, but not all colors stored in the vocabulary represent the cars owned by <em>Visitor</em>. He would like to filter the select options list to the colors of his own cars, or to the colors of the cars of his friends.</p> <p><strong>Usage</strong><br> <a href="http://drupal.org/sandbox/panchiniak/1521136" title="sandbox">Tefiltro</a> filters the options list of a term reference filed in a node add/edit form. Configure admin/config/content/tefiltro. Fill the form with:</p> <ul> <li><em>Target Field</em>, </li> <li><em>Origin Field</em> and </li> <li><em>Target Content Type</em>.</li> </ul> <p>Note: <em>Target Field</em> is the field used to select previsouly created terms, while <em>Origin Field</em> is the term reference field used to create terms that will be then selected by <em>Target Field</em>.</p> <p><strong>Step-by-Step</strong><br> Although this is a very simple module, its usage can be trick unless you have faced the filtering needings it solves. For overcoming that read the step-by-step guide in the README.txt file.
