Whilst working numerous OpenSource projects I've created various functions for constructing Backbase (client edition) code through a simple PHP class (still in development). One of the most useful functions is combobox creation. With this code you simply pass it a name followed by an array of values. The other options allow you to define a "selected" value, then the size of the combobox and whether or not it is required. The required functionality is not yet implemented into the Backbase control so best ignore it for the time being.
