Inline list / Dynamic column list should be more compact

[aafre]

Currently, each item in the Inline List or Dynamic Column List section takes up the entire width of the page.

Essentially, each item in them would perhaps be restricted to 20-30 chars. So we can improve the UI where on one line, we could potentially have two items (or maybe more?).

We do not want to implement validation/character length restriction in this task but just update the styling so visually we can have more than one item on one line and update the add button accordingly. Validation will be handled in a separate task.
