Hi Mike,

I created a sample and below are screenshots to guide you through this:

1- This is a sample page details to check the cars 

2- I call a nanoflow from the Open Details button, I added a loop to create the links depending on selection, in mine I used helper with the selection and inside the loop a microflow to create links

3- the microflow that we call inside the loop to generate the link of the deeplink that was already configured inside the deeplink module:

4- deeplink microflow:

Thanks,

Nour

Nour explains it well, using the deeplink module. Though if the deeplink module isn't yet part of the model, it would be worth to use the page URL's as deeplink. 

Page property config

/{id} represents the object ID of the dataview context object

Create a nanoflow which is triggered onclick

Hi Mike,

You can use both deeplink and open url activity, first create a deeplink https://docs.mendix.com/appstore/modules/deep-link  of that has your car object as a parameter to pass it, and add your logic of opening your detailed page.
inside that button that you will click on when you select multiple add objects use a nanoflow to be able to use the open url from the nanoflow community https://docs.mendix.com/appstore/modules/nanoflow-commons  :
1. add a loop to iterate over the selected cars
2. first activity in the loop, create the deeplink url of each object iterator 
3. call the open url activity ( if the community nanoflow does not allow open new tab, you can modify it or create similar to your own as a best practice) I created similar to my own to open a new tab before.

Thanks,

Nour
