Thanks Ryan. I tried using more correct html but I still got the same parsing error: "Closing tag </li> on line 28 is improperly nested with tag <span> on line 27." So I don't know of a way to put the closing tags in an If component. And if I try to put the tags in the bindings, I get a different parse error: <component id="insertUlTag" type="Insert"> <binding name="value" value="'<ul>'"/> <binding name="raw" value="true"/> </component> "Unable to read context:/WEB-INF/MyDiscussion.page: The value of attribute "value" associated with an element type "binding" must not contain the '<' character." So, I guess using a custom library of open and close tags may just be the best way to go.
