How to create an editable list in a guided landing page template

I'm trying to add a dynamic list where you don't need to specify the number of items beforehand.

So far I'm using the following, but it seems like there must be a more efficient way to do this, particularly if dozens of list items need to be added in certain instances:

<ul>

            <li id="listItem1" style="display:${showListItem1};">

              <div class="mktoText" id="listText1" mktoName="List Item 1">

                List Item 1

              </div>

            </li>

            <li id="listItem2" style="display:${showListItem2};">

              <div class="mktoText" id="listText2" mktoName="List Item 2">

                List Item 2

              </div>

            </li>

            <li id="listItem3" style="display:${showListItem3};">

              <div class="mktoText" id="listText3" mktoName="List Item 3">

                List Item 3

              </div>

            </li>

          </ul>

Thanks for having a look.
