Greetings, I'm presented with the following situation: I am creating a schema for a wine degustation. One of the the fields describing the wine, the colour of the wine (field: wine_colour), is implemented like a Choice field. Red, white and roseé wines (field: wine_type) have different possible shades of colour and I have one vocabulary devoted to each kind of wine. Now my problem: During the editing of the schema, I need the right vocabulary (shades_red, shades_white, shades_rosee) to be linked as source for the Choice field (or the <option> items to populate the <select> tag int he html page if you prefer) and the wine_type of the schema tells me which vocubulary to use. This is a dynamic bind.
