Change List Sizing

I have defined a list with one row of data and three more optional rows of data

Row 1 is always shown - rows 2, 3, and 4 are shown if there is data available in those fields

By using the visiblity property I can have rows 2, 3, and 4 disapper when no data is available and appear when data is available

What I would like to do now is change the height of the list item based on if rows 2, 3, or 4 are visible (have data)

So if no data is available then the list item would only be one row high

If only one of rows 2, 3, or 4 contain data then the list item would be two rows high

so forth and so on

I noticed that the textbox can increase and decrease height to accomodate content. Looking for something similar in a list item.


Thanks!
