Repositories
A repository is where area items store their state. This allows groups of area items to interact with each other.
An example of this would be when clicking on a chart to filter a table, or using an table's selection to provide records for an action.
You can manage the repositories for your layout by clicking on the Repositories button in the command bar
In the repositories modal you can add a new repository from the command bar, or change how you would like multiple filters to be handled for a specific repository.
Filter Templates
Filter templates allows you to add a filter to the repository.
The template used to create the criteria that will get applied
You can include your layout variables in these templates by pre-pending them with an @. To lean more above variables see Variables.
For example:
[Duration] < @limit AND [EndOn] < @end
