How to make div expand only from bottom to bottom

Question

I have a div in modal below. The problem I am facing is when I click Add Row, it creates another div with a row and extends the top and bottom. After several lines have been added, the div will turn off the screen. See screenshots. Note. The query-row element is an angular directive, so you do not see a template for it (which includes the actual fields and the add row button). But it does not matter in this case.

HTML

<div class="ng-modal ng-cloak" ng-show="true">
    <div class="ng-modal-overlay">
        <div class="ng-modal-close">
            <div class="ng-modal-close-x">CLOSE</div>
        </div>
        <div class="ng-modal-dialog">
            <div class="ng-modal-dialog-content">
                <div class="document-content-wrapper">
                    <div class="document-content">
                        <div ng-repeat="row in rows">
                            <query-row rows="rows" remove-row="removeRow(row)" add-row="addRow()"></query-row>
                        </div>
                        <div class="row">
                            <button ng-click="submit()" class="btn btn-primary">Submit</button>
                            <button ng-click="cancel()" class="btn btn-info">Cancel</button>
                        </div>
                    </div>
                </div>
            </div>
        </div>
    </div>
</div>

<table>

</tr>
 </thead>
  <tbody>
   <tr ng-repeat="rowContent in rows">
      <td>{{rowContent}}</td>
     </tr>
