Another option is to use Contional show option on the object that you want to be popped up.
1 Create a variable (CTRL+ALT+ v) Add : vShow
2 Create a button and add action Set Variabel
Variable : vShow
3 Go to the Layout tab of the object you want to show with the button
4 Click the dot on Show Conditional and give as value : vShow =1
By pressing the button the varaible vShow changes from 0 to 1 (and back)
and the object will dissaper and show by bressing that button.
