container div height w overflow

[jimfog]

I have a container with list items:

    <fieldset id="column_contai">
        <ul>
            <li>maria</li>
            <li>anthi</li>
            <li>Nikos</li>
           <li>maria</li>
            <li>anthi</li>
            <li>Nikos</li>
             <li>maria</li>
            <li>anthi</li>
            <li>Nikos</li>
           <li>maria</li>
            <li>anthi</li>
            <li>Nikos</li>
        </ul>
            </fieldset>

I want the height to be auto adjusted depending on the content and when it reaches a threshold(PX for example)...hide the rest and display a scrollbar.

I know that the last one is a metter of overflow but I do not kbow how to achieve the first feature.

Setting max-height with overflow would do it, as long as your element is a block type.
