Hello Laurent
As you selection is fortunately a single selection such a query is fairly easy. So alltogether I would create such a selectbox like this:
- Fetch the class attribute for this object attribute to get an array with the ids and the corresponding clear names of all options.
- Go through each item in this array and make a simple fetch to check whether there is at least one object where the current option is selected. Something like this:
{set $testNodesArr = fetch('content', 'tree', hash ('parent_node_id', 2,
'limit', 1,
'attribute_filter', array( array( '<your_class>/<your-selection_attribute_identifier>', '=', <id of current option>))))}
If possible, it might be a good idea to use a better parent node and use list instead of tree. Also an limitation to the class type might be good, I was just to lazy to look up the proper syntax.
If $testNodesArr exists and has at least one item, there is a object where the current option is selected so add this option to the selectbox. As you can see this is something which should be well cached. Greetings from Luxembourg Claudia
