Ordered / unordered lists in Wappler

Wappler does not recognize the tags in the App Structure
< ul > < li > < / li > </ ul> "
or
< ol > < li > < / li > < / ol > "
although they are listed in the bootstrap4 descriptions.
Is there a special reason for this?

Now I can select them in the DOM and style them in Design. But I can not style (e.g. margins) them according to the viewport dimensions.
