Indicates if the element is collapsed or expanded.
If collapsed
is true
, the element is not displayed on the page under
any circumstances. However, the collapsed element is still in the site's DOM. Unlike a
hidden
element, a collapsed element doesn't take up any
space on the page. When collapsed, elements positioned within 70 pixels
below the collapsed element and each other move up to take the
collapsed element's place where possible. The elements that move up
maintain their positions relative to one another.
If collapsed
is false
, the element may be displayed on the page.
Elements that moved up to take the collapsed element's place on the
page are moved back down.
However, an expanded element (an element whose collapsed
property is
false
) is still not displayed if:
hidden
.Even if the element is not displayed due to the conditions
mentioned above, if its collapsed
property is false
, it's
displayed when the conditions no longer apply.
To set the collapsed
property on an element, use the element's
collapse()
and expand()
functions.
If you select Collapsed on load in the element's Properties panel
in the Editor, the collapsed
property is set to true
when the page loads.
