Indicates if the element is visible or hidden.
If hidden is true, the element is not displayed on the app under
any circumstances. Unlike a
collapsed element, a hidden element continues to
take up the same space on the app as it did when it was visible.
If hidden is false, the element may be displayed on the app.
However, an element whose hidden property is false is still not
displayed if:
collapsed.Even if the element is not displayed due to the conditions
mentioned above, if its hidden property is set to false, it's
displayed when the conditions no longer apply.
To determine if the element is actually visible, use the
isVisible property.
To set the hidden property on an element, use the element's
hide() or show() functions.
If you select Hidden on load in the Properties panel
in the Editor, the hidden property is set to true when the app loads.
Note: An element's hidden property is not the same as its
isVisible property. The hidden property
indicates whether the element should be displayed, while isVisible
indicates if it is actually displayed.
