Select options can be provided using one of three different methods: 1. key=value pairs, one per line, as for a selectbox 2. @filename.php - The file must be in the egw root, and define an array named $options, that has key => value pairs 3. Define the options normally used for the AJAX Select widget (get_rows, get_title, id_field) and it will pull values from the database, as normal. Other options (icon, filter, template, link) can be used regardless of the method used to get the values.
