Actually, there is popup in another page. And in another page i am making the same button, so it it possible to open another page popup by clicking current page button.
What do you mean by “same button”? Is your button a reusable element?
i mean both function same, for ex if there is login button in two different page but same workflow
You can place your button in a reusable element (like header or a separate reusable group just with that button) to show it on every page you need using same WF for each page of your app.
