EL providing indentation dots

[Pat Farrell]

I need to produce an indented list and wonder if a pure EL structure can make it happen. An example list would look like


Bear
. motorcycle
. . Harley
. . Yamaha
. car
. . Yugo
Pat
. motorcycle
. . Hodaka
. . Yamaha
. car
. . Pontiac
. . Lincoln

I've got a EL variable ${indent} for each record
Is there some way to do something like

for (int i = 0, i < ${indent}; i++ ) {
" . "
}

There is no way to loop with just the EL. You'll need the JSTL forEach action for that.

(Or create a custom tag, or EL function, for this specific purpose.)

And, Bear drives a Mazda MX-5.

This does the trick

<c:forEach var="i" begin="1" end="${entry.indent}" step="1">
. 
</c:forEach>

Wow, Bar, that's a small car, its almost lighter than your current Yahama

I guess it's as close to a motorcycle I could get in a car.
