Combination box options

[BayesTex]

Hi there,

I am having problem with forms, because I understand that
one can built a form with combination boxes, where one can choosing
the wanted option, I mean, Choose between several items
inside the table, write it as new item, or search
a registry similar to it inside the form.

I want use the first two options, choosing the item between the listed
options, or if the option doesn't exist, one can write the new option,
that will be part of original table.

When I tryed this, the sistems give me a warning, saying
this is an invalid step.

How can I implement the first two options, choose or write one,
without the sistems fails.

Thanks in advance,

they're more commonly called combo boxes here, and choosing from the list is their standard use. to add a new value to the list, you have to use the notinlist parameter.

try searching for combo, combobox, or notinlist and you'll find lots of discussions.
