Best Way to Enable Multi-Database Selection in H2O GPT?

[BhoomikaMuralidhara]

Hello,
I’m trying to implement a feature in H2O GPT where users can select multiple databases in real-time using checkboxes, and the system queries all selected databases dynamically as the selection changes. My goals are:

Allow users to select or deselect databases (via checkboxes) dynamically.
Perform queries in real-time based on the current selection.
Combine results from all selected databases into a single response.
I’m working with the evaluate_nochat function and want to modify:

langchain_mode to support multi-selection (as a list).
Query logic to dynamically loop through the selected databases and update results in real-time.
If anyone has experience with real-time query updates or can suggest the best approach to achieve this, I’d really appreciate your insights!

Thanks in advance!
