With the Custom HTML you can only set the html pper item. Not the surrounding (container) html.
If you want full control of what html you place around the entire list of items, use a template layout override for the field.
Peter,
Can you provide a little guidance on the template layout override for the field?
1. Which field HTML am I creating a new layout for?
2. If I create a new layout can I select the layout for the specific field only? How would I do that?
we were able to figure out a way to do this with CSS / bootstrap... maybe this can be added in as an option:
1. Created a specific class for the image field to include object-fit: cover, and a specified width and height, this way the image would display as a square
2. Articles Field setup
Tab: Options Class
Display options: value class: d-flex flex-wrap
The way you solved this is one of the ways you can.
How to style things is down to the css and template (and whatever custom html you want to output).
This is outside the scope of Articles Field to control. So it won't be added as a 'ready-to-use' option.
