Is it difficult to make drop downs and check boxes required?

[rwilki]

In theory, I know how to make any form element a required item. My question is two-fold:

1) I'm going to have 3 choices of check boxes, for example, it could be [ ] dog, [ ] cat, or [ ] other. Since I need my visitors to choose at least one of them, but maybe all of them, how do I mandate that they at least select one?

2) I'm going to use a drop down list box for choice of states. How do I make this so that my visitor actually drops down the list to actually choose a state? - I'll need to find a pre-defined option list for this so that I don't have to manually code all this content.

Is this something for conditions?

Thanks,
Bob

You just need to make sure that all of the checkboxes in a particular group have the same "name", then make that field required.

For select boxes:

<select name="state"><option value="">Choose State</option><option value="Alabama">Alabama</option>
<option value="Arizona">Arizona</option></select>

Make sure that your first option has an empty "value". In my example, that would be the Choose State option. Then, make the "state" field required.
