Here the 1st dropdown in the one template and the below dropdown was a another template.

in both the dropdown I have used query binding, by the 1st value of the dropdown the used for the where condition in the second dropdown.

I have create a custom param(as global) then bind it as bidirectional for single instances its working...

while I chose another value in 1st dropdown it changes for all instance because it was bind into global parameter...

What do you mean by this?

- Do you mean you created a property in `session.custom`? (these are global to the active session)
- Do you mean you created a property in your template dropdown View's `params` area as an output and bound it? (these are global in the sense that the binding will be the same for all instances of the View)
- Do you mean you created a property in your template dropdown View's `custom` area and bound it? (same as above)
- or something else?

You seem to have already located your issue here.  
You should be adding the binding to the Embedded View's `props.params.<propName>` instead of hardcoding it into the template View itself

Dear Nick Minchin,

yes, the second point is right. need to check a new logic for all instances of the View.
