expand( )
Expands the element and sets its collapsed
property to false
.
The expand()
function returns a Promise that is resolved when the
element's collapsed
property has been set to false
.
To learn about the behavior of an expanded element,
see the collapsed
property.
Notes:
-
In Editor X, an element will not become visible by using
expand()
if it has been marked as "Don't Display" for the current breakpoint. Callingexpand()
will however, change thecollapsed
property of the element tofalse
. -
It is recommended not to mix
expand()
andcollapse()
with "Don't Display" in Editor X.
