Zend Framework 2: How to generate multiple selects on a form?

Question

Zend Framework

Point in the right direction. It is necessary to generate many select-ov in the form.
For example

<select name="cat[1]">
  <option value="1">1</option>
  <option value="2">2</option>
</select>
<select name="cat[2]">
  <option value="1">1</option>
  <option value="2">2</option>
</select>
<select name="cat[3]">
  <option value="1">1</option>
  <option value="2">2</option>
</select>

To add that, for example, I can them after creation of object of the form. But how do I then process these generated elements in the InputFilter? I do not know in advance the number of elements in the cat array.
