Can more than one item on a drop-down list be selected?

[Christine]

I'm creating an application where the applicants are teachers. Since
teachers teach multiple subjects, how do I allow them to select more than one
subject on a drop-down list?
Please keep the answer simple. Thank you.

Hi,
You can use multiple selection box for this. Go through the below link once.
It will tell you how to insert a multiple selection box.

Hi,

Add a repeating section and place the subject drop down in that section.
Create a secondary xml for subjects and get the values for subject drop down
from this xml. Your xml should be like this
<subjects>
<subject>1</subject>
<subject>2</subject>
<subject>3</subject>
</subjects>

Then use the following expressions as filter conditions

not(. = current()/preceding-sibling::my:group2/my:subject)
not(. = current()/following-sibling::my:group2/my:subject)

Here group2 is repeating group in main data source and subject is subject
drop down.
