[TYPO3-dev] Frontend plugin - storing a list of objects

[Boros Attila]

Hello,

I need to store the properties of meeting rooms in a frontend plugin.
In the frontend it should look like a table:

+-----------+---------------+-------------+-------------+
| Room name | Square meters | Seat type 1 | Seat type 2 |
+-----------+---------------+-------------+-------------+
| Pietro    |      46       |     60      |      30     |
+-----------+---------------+-------------+-------------+
| Pio       |      37       |     40      |      24     |
+-----------+---------------+-------------+-------------+

There can be any number of rows. I'm trying to create a new extension
with the kickstarter but there is nothing like "list of something" in
the field type list. How could I do this?

Thanks in advance,
Attila
