If Statement with check box and list

[LGNgirl]

Im using a checkbox using an if statement that looks like:

=IF(B2=TRUE,E2:E4)

Now E2 is apple
E3 is pear
E4 is orange

What I want to happen is that when I check the check box I want E2,E3,and E4 to show up like:

apple
pear
orange

It is only showing E2 (apple)

I tried =IF(B2=TRUE,E2&E3&E4) and got closer but it is only appearing as:

applepearorange

How do I get it to appear in columns than one row?

Thankyou for your help
