Is there a way to allow a user to select more than one option form a drop-down list?

Trying to give users the option to select more than one option when selecting from a drop-down on a PDF. I have seen where it may be possible using javascript, but am unable to locate the exact script needed to enter to make it work.

You can use a list box.

I appreciate the response!

Yeah, seems to be the only way. Don't think it will work for me unless there is a way to have a list box function like a drop down. List box has all the option showing at once. I have two drop down boxes where one affects the other. using javascript.

ie. Drop down box 1 has options a-d

If I select option a, drop down box 2 gives me options to choose from (where I want mulitple options selected, but only want to see the options I select and not the ones I don't).

If I select option b in drop down box 1, drop down box 2 will have no options to choose from. So on and so forth....

You can set the options under Box 2 based on the selection in Box 1 (using a script), but you can't select more than one option at a time. The only other way of doing something like that is to use a pop-up menu, triggered by a button, where more than one option can be "ticked", but that requires a more complex scripting solution.
