This style inspector setting lets you show and hide elements. You can switch between visible, hidden and collapsed.



You can also use the display pop-over from the style bar.



Hidden

Just makes the element invisible, but the element still affects the layout.

Visible

Shows the element.

Collapse

Removes the elements completely, the layout is not affected.

Opacity

In addition, the opacity of the element can be changed. All nested elements are also affected by the opacity setting.

z-index

You can specify the painting order within a container. Elements with a higher z-index are behind later and show up above other elements with a lower z-index.

Paint above all

Independent of the hierarchy and layout, paint above all paints the object above all other elements. This is especially useful for pop-up menus.
