Dropdown Search Bar Inside Layout Doesnt Work

Hello all, In the current app that i ve been working on, I want to locate a dropdown  search bar inside layout. After i filter , my expectation is filtering all the datagrids in several pages. In order to do that, i need to put a dataview that cover all the  Main section and Create a helper. However i can not put a dataview directly inside layout that need to cover Main and Menu sections. If i extract it into snippet, doesnt cover the entire Main page as well. After locating a search bar , means every page search bar need to be accessable and using the same Helper entity. Can you please guide me what is the best practice ? Thanks

Could you not attach the helper object to the user session? This way you can retrieve it everytime based on the current user.
