Hi Joseph,
You can remove all Mendix styling from a listview by changing the Style to ‘No Styling’.
If you want to add your own styling, you can add a class on your listview:
And add the required styling in the custom stylesheet (requires some knowledge of CSS/SCSS, depending on what you want to achieve):
.mycustom-listview {
//Enter custom styling here
}
Mendix has a learning path about this here. Hope this helps!
Cheers
