Use a horizontal filter strip or a vertical panel, with clear boundaries and readable selections.
Rows, columns and compact sizing
Responsive layout wraps controls into rows/columns and supports preferred row/column counts. Mixed control types adapt; dropdowns are the compact default. Lists scroll internally when content exceeds the available space. Slicer text defaults to 9 px and container corner rounding to 3 px.

Outer versus inner padding
Container → Outer padding controls the gap between the drawn border and visual boundary: individual sides or uniform 0–100 px. Inner padding is the content inset. Quick periods has independent heading/button/informative-text fonts, size, padding, gaps, checkbox size and colors. Opening Quick periods moves following fields down; closing it reclaims that space.
Collapse follows the drawn container
Collapse/expand changes the box’s own border and background. Power BI retains its allocated canvas rectangle and selection frame; the custom visual cannot shrink that host rectangle. Use the Container border/background and disable the native border/background when only the moving outline should be visible.
Small text, usable hit area
Checkbox appearance and option-row height can be compact while the whole row stays clickable. Use larger settings where accessibility or touch interaction needs more space.
