Delete an Element from other pages and retain it in one page

Question:
I have created a project pages layer. I want have added an element in one of the pages, but it’s repeated in all the pages. Is there any way I can keep the element in one page and delete those in other pages?

Is it a dynamic page?
If so, you can have a Boolean field in the CMS (e.g. staticContent)

Set the contents to be automatically hidden/collapsed

Then in the page code, you can do something like this:

item = $w('#dynamicDataset').getCurrentItem()
if (item.showStatic) $w('#staticContent').show()   // or expand()
